As of the 2010 census, it had a population of 395,326 making it the 46th - largest city under the jurisdiction of the United States. San Juan was founded by Spanish colonists in 1521, who called it Ciudad de Puerto Rico ( `` Rich Port City '' ). Puerto Rico 's capital is the second oldest European - established capital city in the Americas, after Santo Domingo, in the Dominican Republic. Several historical buildings are located in San Juan ; among the most notable are the city 's former defensive forts, Fort San Felipe del Morro and Fort San Cristóbal, and La Fortaleza, the oldest executive mansion in continuous use in the Americas. Today, San Juan is Puerto Rico 's most important seaport, and is the island 's manufacturing, financial, cultural, and tourism center. The population of the Metropolitan Statistical Area, including San Juan and the municipalities of Bayamón, Guaynabo, Cataño, Canóvanas, Caguas, Toa Alta, Toa Baja, Carolina and Trujillo Alto, is about 2 million inhabitants ; thus, about half the population of Puerto Rico now lives and works in this area. San Juan is also a principal city of the San Juan - Caguas - Fajardo Combined Statistical Area. The city has been the host of events within the sports community, including the 1979 Pan American Games, 1966 Central American and Caribbean Games, events of the 2006, 2009 and 2013 World Baseball Classics, the Caribbean Series and the Special Olympics and MLB San Juan Series in 2010.

It was named after the Province of Caceres in Spain, the birthplace of Nicolás de Ovando, then the Governor of Spain 's Caribbean territories, Today it is part of the Pueblo Viejo sector of Guaynabo, just to the west of the present San Juan metropolitan area. A year later, the settlement was moved to a site then called Puerto Rico, Spanish for `` rich port '' or `` good port '', after its similar geographical features to the town of Puerto Rico of Gran Canaria in the Canary Islands. In 1521, the newer settlement was given its formal name, Puerto Rico de San Juan Bautista. The ambiguous use of San Juan Bautista and Puerto Rico for both the city and the island in time led to a reversal in practical use by most inhabitants : by 1746 the name for the city ( Puerto Rico ) had become that of the entire island, leading to the city being identified as Puerto Rico de Puerto Rico on maps of the era. San Juan and bay, Puerto Rico, 1766 San Juan, as a settlement of the Spanish Empire, was used by merchant and military ships traveling from Spain as the first stopover in the Americas. Because of its prominence in the Caribbean, a network of fortifications was built to protect the transports of gold and silver from the New World to Europe. Because of the rich cargoes, San Juan became a target of the foreign powers of the time. The city was witness to attacks from the English led by Sir Francis Drake in 1595 ( in what is known as the Battle of Puerto Rico ) and by George Clifford, Earl of Cumberland, in 1598. Artillery from San Juan 's fort, El Morro, repelled Drake ; however, Clifford managed to land troops and lay siege to the city. After a few months of English occupation, Clifford was forced to abandon the siege when his troops began to suffer from exhaustion and sickness. In 1625 the city was sacked by Dutch forces led by Captain Balduino Enrico ( also known as Boudewijn Hendricksz / Bowdoin Henrick ), but El Morro withstood the assault and was not taken. The Dutch were counterattacked by Captain Juan de Amezquita and 50 members of the civilian militia on land and by the cannons of the Spanish troops in El Morro Castle. The land battle left 60 Dutch soldiers dead and Enrico with a sword wound to his neck which he received from the hands of Amezquita. The Dutch ships at sea were boarded by Puerto Ricans who defeated those aboard. After a long battle, the Spanish soldiers and volunteers of the city 's militia were able to defend the city from the attack and save the island from an invasion. On October 21, Enrico set La Fortaleza and the city ablaze. Captains Amezquita and Andre Botello decided to put a stop to the destruction and led 200 men in an attack against the enemy 's front and rear guard. They drove Enrico and his men from their trenches and into the ocean in their haste to reach their ships. The British attack in 1797, during the French Revolutionary Wars, led by Sir Ralph Abercromby ( who had just conquered Trinidad ). His army laid siege to the city but was forced to withdraw in defeat as the Puerto Rican defenses proved more resilient than those of Trinidad. Various events and circumstances, including liberalized commerce with Spain, the opening of the island to immigrants as a direct result of the Royal Decree of Graces of 1815, and the colonial revolutions, led to an expansion of San Juan and other Puerto Rican settlements in the late 18th and early 19th century. La Plaza, San Juan, ca. 1900 On May 8, 1898, United States Navy ships, among them the USS Detroit, USS Indiana, USS New York, USS Amphitrite, USS Terror and USS Montgomery, commanded by Rear Admiral William T. Sampson arrived at San Juan Bay. The USS Yale captured a Spanish freighter, the Rita in San Juan Bay, thus being the first hostile encounter between the warring sides in Puerto Rico. On May 9, Yale fought a brief battle with an auxiliary cruiser of Spain, name unknown, resulting in a Spanish victory. Around this time, Captain Ángel Rivero Méndez was assigned the command of the Spanish forces in the fortress of San Cristóbal in San Juan. On May 10, the Yale returned to San Juan Bay, Rivero - Méndez ordered his men to open fire upon the USS Yale using an Ordoñez 15 centimeter cannon, thus becoming the first attack against the Americans in Puerto Rico during the Spanish -- American War. For his actions, Captain Rivero - Mendez was awarded the `` Cruz de la Orden de Merito Militar '' ( The Cross of the Order of the Military Merit ) first class. The residents of San Juan were furious with Rivero and blamed him for the destruction caused to their city by the American bombardments. Nothing came of those accusations and Capt. Rivero - Méndez was ordered to turn over the keys of all the military installations in San Juan to Captain Henry A. Reed of the U.S. Army after the Treaty of Paris of 1898 was signed. On July 25, General Nelson A. Miles landed at Guánica ( in southwestern Puerto Rico ) with 3,300 soldiers in what was known as the Puerto Rican Campaign. The American troops found some resistance and engaged the Spanish and Puerto Rican troops in battle, the most notable of these the battles of Yauco and Asomante. All military actions in Puerto Rico were suspended August 13, 1898, after President William McKinley and French Ambassador Jules Cambon, acting on behalf of the Spanish government, signed an armistice. Spain ceded the island to the United States later the same year by signing the Treaty of Paris. Camp Las Casas, located in the district of Santurce, served as the main training camp for the Puerto Rican soldiers prior to World War I and World War II ; the majority of the men trained in this facility were assigned to the `` Porto Rico Regiment of Infantry '' which was renamed the 65th Infantry Regiment of the United States Army by the Reorganization Act of June 4, 1920. The 65th Infantry was deactivated in 1956 and became the only unit ever to be transferred from an active Army component to the Puerto Rico National Guard. Shanty town along the Martín Peña Canal, 1973 Lieutenant Teófilo Marxuach ( Retired as a Lieutenant Colonel ), a native of Arroyo, Puerto Rico, fired the first shot in what is considered to be the first shot of World War I fired by the regular armed forces of the United States against any ship flying the colors of the Central Powers Marxuach, who was a member of the `` Porto Rico Regiment of Infantry '' and Officer of the Day, on March 25, 1915, opened fire on the Odenwald, an armed German supply vessel, when it was trying to force its way out of San Juan 's bay. The shots ordered by Lt. Marxuach were the first fired by the United States in World War I. In 1919, Félix Rigau Carrera, `` El Aguila de Sabana Grande '' ( The Eagle from Sabana Grande ), the first Puerto Rican pilot, became the first native Puerto Rican to fly an aircraft in the island when he flew his Curtiss JN - 4 from Las Casas. At the time, the area was used by the military as an air base and it was also Puerto Rico 's first commercial airport, and Rigau Carrera was allowed to perform his historic flight from the air field. Camp Las Casas was eventually closed down, and in 1950 a public housing project by the name of Residencial Fray Bartolome de Las Casas was constructed on its former location. On January 2, 1947, the people of San Juan elected Felisa Rincón de Gautier ( also known as Doña Fela ) ( 1897 -- 1994 ) as their mayor. Thus, she became the first woman to be elected as the mayor of a capital city in any of The Americas. During the Cold War era, she ordered the establishment of the island 's first Civil Defense system under the directorship of Colonel Gilberto José Marxuach ( Teófilo 's son ). Rincón de Gautier served as mayor until January 2, 1969. Historic coat of arms of San Juan ( Spanish rule ) On October 30, 1950, San Juan was the scene of the San Juan Uprising, one of many uprisings which occurred in various towns and cities in Puerto Rico, by the Puerto Rican Nationalist Party against the governments of Puerto Rico and the United States. Among the uprising 's main objective was to attack `` La Fortaleza '' ( the Governors mansion ) and the United States Federal Court House Building in Old San Juan. In accordance to the planned uprising in San Juan, a group of nationalists were supposed to attack simultaneously the gubernatorial mansion La Fortaleza, where Puerto Rican governor Luis Muñoz Marín resided, and the United States Federal Court House which is located close to an area called `` La Marina '' in Old San Juan. The La Fortaleza battle, which ensued between the nationalists and the police lasted 15 minutes, and ended when four of the five attackers were killed. Coat of Arms and flag of San Juan Main article : Diego de Torres Vargas On March 8, 1948 the city government of San Juan officially adopted as the city 's first flag an orange field, in the center of which is the Coat of Arms of the City. The orange color was based and taken from Father Diego de Torres Vargas ' text and it reads : `` Escudo de armas dado a Puerto Rico por los Reyes Católicos en el año de 1511, siendo Procurador un vecino llamado Pedro Moreno. Son : un cordero blanco con su banderilla colorada, sobre un libro, y todo sobre una isla verde, que es la de Puerto Rico, y por los lados una F y una I, que quiere decir Fernando e Isabel, los Reyes Católicos que se las dieron, y hoy se conservan en el estandarte real, que es de damasco anaranjado, con que se ganó la ciudad '' ( `` Coat of Arms given to Puerto Rico by the Catholic Monarchs in the year 1511 being Procurator a vecino named Pedro Moreno. They are : a white lamb with a red flag, on top of a book, and everything above a green island, which is Puerto Rico... which is of orange damask, with which the city was won '' ). It appears that the color was changed from orange to white at some point. 17th - century Spanish painting commemorating Captain Juan de Amezquita 's victory and Enrico 's defeat at Puerto Rico de San Juan ; by Eugenio Caxés, Museo del Prado Castle San Felipe del Morro Rigau Carrera poses in his plane ( 1919 ) Lieutenant Teofilo Marxuach The bodies of two nationalists lie on the ground after their attack on La Fortaleza ( 1950 ) Coat of arms of San Juan Geography San Juan from space San Juan is located along the north - eastern coast of Puerto Rico. It lies south of the Atlantic Ocean ; north of Caguas and Trujillo Alto ; east of and Guaynabo ; and west of Carolina. The city occupies an area of 76.93 square miles ( 199.2 km ), of which, 29.11 square miles ( 75.4 km ) ( 37.83 % ) is water. San Juan 's main water bodies are San Juan Bay and two natural lagoons, the Condado and San José. Climate San Juan has a tropical monsoon climate and enjoys an average temperature of 81.0 ° F ( 27.2 ° C ) although 90 ° F ( 32 ° C ) or higher temperatures are seen on an average 79 days annually, more commonly occurring during the wetter months of the northern summer, especially if the winds come from the south. In the winter, temperatures can drop to around 60 ° F ( 16 ° C ), though the average winter low is 71 ° F ( 22 ° C ). The coolest temperature officially recorded was 60 ° F ( 16 ° C ) on March 3, 1957, and the hottest was 98 ° F ( 37 ° C ) on October 9, 1981 ; the record cold daily maximum is 71 ° F ( 22 ° C ) on February 4, 1935, while the record warm daily minimum is 83 ° F ( 28 ° C ) on August 11, 1995, the most recent of four occasions. Rainfall is well - distributed throughout the year, but the months of January, February, and March are the driest ; as March averages just 1.95 inches ( 49.5 mm ) of rain, the city falls under the tropical monsoon category. Rainfall averages 56.35 inches ( 1,431.3 mm ), falling on an average 198.5 days per year ; despite this dampness, the city averages 2,970 hours of sunshine per year, or just over 2⁄3 of the possible total. Annual rainfall has historically ranged from 35.53 in ( 902 mm ) in 1991 to 89.50 in ( 2,273 mm ) in 2010.

The clock tower building at center was the San Juan Rail Terminal. Architecture Old San Juan The architecture of San Juan is very diverse, due to its size and all the cultural influences received during its existence. The oldest part of the city, known as Old San Juan, mostly features the influence of Spanish architecture. This part of the city is comprised by a network of `` setted '' roads usually surrounded by ancient, two - storied houses built on masonry. Some colonial structures have been restored and serve either as government offices or museums. Some examples are the Ballajá Barracks, which now serve as museum and headquarter of several cultural organizations ; La Fortaleza, which has served as the residence of the Governor of Puerto Rico since the 16th Century ; and the Ancient Welfare Asylum, which now houses the Institute of Puerto Rican Culture, among others. Old San Juan also features several public squares, like the Plaza de Armas, located in front of San Juan City Hall ; and cathedrals, like the Cathedral of San Juan Bautista. Old San Juan is also notable for being partly enclosed by massive walls and fortifications built by the Spanish government. The architecture is more varied in other districts of the city. The district of Santurce features a lot of influence from art deco, while the districts of Hato Rey feature more modern structures. Districts Districts of San Juan Main article : Subdivisions of San Juan, Puerto Rico What is now known as Old San Juan occupied the western end of a rocky islet, the Isleta de San Juan, at the mouth of San Juan Bay. During the 20th century, the main population centers surged well beyond the walls of the old city and onto Puerto Rico 's main island, and merged with the existing settlements east and south of Old San Juan. With the annexation of Río Piedras in 1951, the municipality of San Juan grew four times its previous size. As a result, the city is now composed of a variety of districts and neighborhoods. San Juan is now subdivided into 18 districts ( barrios ), 16 of which fall within the former municipality of Río Piedras. Eight districts are further subdivided into sectors ( sub-barrios ), including two districts in the area that covered the original municipality of San Juan. The 18 districts are : Caimito Cupey El Cinco Gobernador Piñero Hato Rey Central Hato Rey Norte Hato Rey Sur Monacillo Monacillo Urbano Oriente Pueblo Quebrada Arenas Sabana Llana Norte Sabana Llana Sur San Juan Antiguo ( Old San Juan ) Santurce Tortugo Universidad Old San Juan Main article : Old San Juan, Puerto Rico Some streets in Old San Juan are still paved with blue cobblestones from the Spanish colonial era. During the Spanish colonial times most of the urban population resided in what is now known as Old San Juan. This sector is located on the western half of a small island called the Isleta de San Juan, which is connected to the mainland by two bridges and a causeway. The small island, which comprises an area of 47 square miles ( 120 km ), also hosts the working - class neighborhood of Puerta de Tierra and most of Puerto Rico 's central government buildings, including the Commonwealth 's Capitol. The main central part of the city is characterized by narrow streets made of blue cobblestone and picturesque colonial buildings, some of which date back to the 16th and 17th century. Sections of the old city are surrounded by massive walls and several defensive structures and notable forts. These include the 16th - century Fort San Felipe del Morro and the 17th - century Fort San Cristóbal, both part of San Juan National Historic Site, and the 16th - century El Palacio de Santa Catalina, also known as La Fortaleza, which serves as the governor 's mansion. Other buildings of interest predating the 20th century are the Ayuntamiento or Alcaldía ( City Hall ), the Diputación Provincial and the Real Intendencia buildings, which currently house the Puerto Rico Department of State, the Casa Rosa, the San José Church ( 1523 ) and the adjacent Hotel El Convento, the former house of the Ponce de León family known as Casa Blanca, the Teatro Tapia, the former Spanish barracks ( now Museum of Ballajá ), La Princesa ( former municipal jail, now headquartering the Puerto Rico Tourism Company ), and the Santa María Magdalena de Pazzis Cemetery, located just outside the city walls. The Cathedral of San Juan Bautista ( construction began in the 1520s ) is also located in Old San Juan, and contains the tomb of the Spanish explorer and settlement founder Juan Ponce de León. Old San Juan, also known as the `` old city '', is the main cultural tourist attraction in Puerto Rico ; its bayside is lined by dock slips for large cruise ships. Other districts East of Old San Juan lies the wealthy tourist - oriented neighborhood of Condado, which occupies land that used to be owned by entrepreneur Pablo Ubarri Capetillo, a Spanish railroad developer and Count of San José de Santurce under the Spanish colonial period. Beaches such as nearby Ocean Park, popular with swimmers, surfers and kitesurfers, are found all along the district 's Atlantic coastline which is also the locus of numerous hotels. Near Condado are two separate business districts, Santurce and Miramar. Miramar is mainly a residential area rising south of the Condado Lagoon. It comprises the former barrio of Miraflores, as well as drained marshland and landfill over which was built San Juan 's first airport, the Isla Grande airport, which was renamed Fernando Luis Ribas Dominicci Airport in honor of Major Fernando Luis Ribas - Dominicci ( USAF ). Miramar now hosts the Puerto Rico Convention Center as well as some of San Juan Harbor 's cruise ship piers. In 2005 Miramar was designated an historical district of Puerto Rico. Santurce, originally named San Mateo de Cangrejos ( Saint Matthew of the Crabs ), was a settlement for freed African slaves during the early days of the city. After Pablo Ubarri sought permission to link San Juan with Río Piedras proper via steam tramway in 1878, the time it took to travel between both points were shortened and thereby stimulated the colonization and growth of the district. At the beginning of the twentieth century an electric trolley was installed, the township was split into three parts, and its main settlement, merged with the city, was renamed using the Spanish spelling of Santurtzi ( Saint George in Basque ), Ubarri 's birthplace in Vizcaya, Spain. The `` Museo de Arte de Puerto Rico '' ( Puerto Rico Museum of Art ) and other important cultural venues are located in Santurce. Looking down an Old San Juan street towards the bay South of Santurce is Hato Rey, part of the former municipality of Río Piedras. Hato Rey was grazing ground for cattle owned by the royal government ( hence its name, the King 's Herd in Spanish ) as early as the 16th century, and is now considered the financial center of the island. A section of this district is often referred to as Milla de Oro ( actually 0.47 miles or 0.76 kilometers long ) due in part to the many banks and businesses located there. In the southern part of the city is the socially diversified community of Río Piedras. Founded in the mid-1850s, Río Piedras was a separate town which hosted sugar cane plantations and the estates of some of San Juan 's wealthiest inhabitants ( as well as their working class staff ). The Spanish colonial governors also had their summer home there on land which eventually gave way to the main campus of the University of Puerto Rico. In 1951 the municipalities of San Juan and Río Piedras were merged to redefine San Juan 's current city limits. Today Río Piedras comprises the largest area of the municipality of San Juan. and is home to the `` Plaza del Mercado '' ( Río Piedras Marketplace ), the main campus and the Medical Sciences campus of the University of Puerto Rico and the San Juan Botanical Garden. Demographics Race -- San Juan, Puerto Rico -- 2010 Census Race Population % of Total White 268,708 68.0 % Black / African American 73,538 18.4 % American Indian and Alaska Native 3,071 0.8 % Asian 1,750 0.4 % Native Hawaiians / Pacific Islander 36 0.0 % Some other race 32,386 8.2 % Two or more races 15,835 4.0 % San Juan is the largest city in Puerto Rico by population. From 1899 to 1950 the municipality of San Juan excluded the township of Río Piedras. For this reason, population data and land area for the period make reference only to the Antiguo San Juan and Santurce barrios, or subdivisions, of San Juan. The old municipality of Río Piedras constituted the third most populated city of Puerto Rico at the time of its annexation in 1951. Its strategic location south of the capital served as a junction for all the principal ways of transportation of the island and as a geographical entry to San Juan, which are factors that prompted Río Piedras 's dramatic urban development in the 20th century. According to the 2010 Census, the racial composition of San Juan was as follows : White : 68.0 % ( Non-Hispanic Whites : 1.2 % ) Black or African American : 18.3 % ( Non-Hispanic Blacks : 0.3 % ) American Indian : 0.8 % Asian : 0.4 % Native Hawaiian / Pacific Islander : 0.0 % Some other race : 8.2 % Two or more races : 4.0 % Hispanic or Latino ( of any race ) : 98.2 % Among the Hispanic and Latino population, Puerto Ricans are, unsurprisingly, the largest group ; they make up 87.5 % of San Juan 's Hispanic population. People of Dominican descent made up 12.2 % of the Hispanic population, while those of Cuban descent formed 1.7 % of the Hispanic populace. Other Hispanic and Latino groups collectively formed 3.2 % of San Juan 's Hispanic population. There are 13,304 whites of non-Hispanic origin living in San Juan ; 10,571 blacks of non-Hispanic origin living in San Juan. Non-Hispanic whites and blacks form 3.2 % and 2.6 % of San Juan 's population respectively. There are also approximately 562 Asians of non-Hispanic origin in San Juan ; they make up only 0.1 % of the population. However, Asians of Hispanic and non-Hispanic origin together number at 6,342. The vast majority of Asians in San Juan are of Chinese descent ; of the 6,342 Asians, 4,928 are Chinese. Chinese comprise 1.4 % of the population. The only other sizable Asian group in San Juan are Indian Americans ; there are 698 people of Indian descent in the city, forming 0.2 % of the population. There are very small numbers of people of Filipino, Japanese, and Vietnamese ancestry ; none of these groups number more than 100 members. According to the 2006 -- 2008 American Community Survey, 87.5 % of San Juan 's population was native and 12.5 % were foreign - born. Of the native population, 86.9 % were born in Puerto Rico or the United States, of which 75.6 % were born in Puerto Rico and 8.9 % were born in the United States. The remaining 0.7 % were born in a U.S. territory or were born abroad to American parents. The remaining 11.9 % of the population were born outside the United States, Puerto Rico, and U.S. territories. In recent years, an increasing number of Americans not of Hispanic ancestry ( both of African American and of White American descent ) have moved to San Juan. In addition, a large number of Stateside Puerto Ricans have settled in the city upon their return to Puerto Rico. There is also a growing West Indian population, both of Hispanic and non-Hispanic origin.

The Metropolitan Area is served by two airports. The Luis Muñoz Marín International Airport, San Juan 's primary commercial airport, is located eight miles ( 12.9 km ) from Old San Juan in the neighboring municipality of Carolina. The airport accommodates more than 30 domestic and international airlines and is the busiest airport in the Caribbean. It is often referred to as `` The Gateway to the Caribbean '' because it serves as the main connection to the island and the rest of the Caribbean for the United States and vice versa. The area 's secondary airport is the Fernando Ribas Dominicci Airport, which is located directly across the San Antonio Creek or Cano San Antonio from Old San Juan in the Isla Grande district. Dominicci Airport is used mainly by general aviation aircraft, charter flights, and some domestic commercial flights.

Public transport See also : Tren Urbano At 4,300 vehicles per paved mile, San Juan has by far the highest density of vehicles on the road of any country in the world. The city is served by five limited - access expressways and highways and numerous arterial avenues and boulevards, but continues to suffer from severe traffic congestion. The Metropolitan Bus Authority ( Autoridad Metropolitana de Autobuses or AMA in Spanish ) provides daily bus transportation to residents of San Juan, Guaynabo, Bayamón, Toa Baja, Trujillo Alto, Cataño and Carolina through 30 fixed routes. Its fleet consists of 277 regular buses and 35 handicap - accessible buses. AMA 's ridership is estimated at 112,000 on weekdays.

The T5, 21 and 53 buses pass between Old San Juan, Condado and Isla Verde. More information is available at http://sjbus.info/ In an attempt to decrease vehicle dependency and road congestion, the city built a metro system dubbed `` Tren Urbano '' ( `` Urban Train '' ). The 10.7 - mile ( 17.2 km ) line connects to 16 stations. The project, which opened in late 2004, cost $2.25 billion and was more than $1 billion over budget and four years late. The Tren Urbano has received less ridership than was originally projected and has not significantly reduced the city 's automobile traffic, despite a reported 7.5 % ridership increase in 2006 over 2005. There is a planned project to build a `` interurban light rail system '' connecting the cities of San Juan and Caguas. Increased investment in public transportation, however, has not changed the fact that San Juan is an automobile - reliant city and its fast growth has sparked urban sprawl. As of mid-2010, the government has approved plans for a redesign of this Puerto Rican city, featuring a new mass transit system, new roads and intersections, and more beach - access points. No cars will be allowed inside the oldest part of city ( Old San Juan ). The plans hope to remedy previous poor urban planning in the oldest section of the city, the Isleta, while curbing reliance on motor vehicles. The plans for redevelopment also hope to make the city more appealing in order to attract new residents, as San Juan has suffered from a shrinking population over the past 60 years.
