# Sukhothai Historical Park

Sukhothai Historical Park (Thai: อุทยานประวัติศาสตร์สุโขทัย (Pronunciation)) covers the ruins of Sukhothai, literally 'dawn of happiness', capital of the Sukhothai Kingdom in the 13th and 14th centuries, in north central Thailand. It is near the city of Sukhothai, capital of Sukhothai Province.
The city's walls form a rectangle about 2 km (1.2 mi) east-west by 1.6 km (0.99 mi) north-south. There are 193 ruins on 70 km$^2$ (27 sq mi) of land. There is a gate in the centre of each wall. Inside are the remains of the royal palace and twenty-six temples, the largest being Wat Mahathat. The park is maintained by the Fine Arts Department of Thailand with help from UNESCO, which has declared it a World Heritage Site. Each year, the park welcomes thousands of visitors.

## History
### Khmer Era

Originally, Sukhothai was a Khmer empire's outpost named Sukhodaya. During the reign of Khmer Empire, the Khmers built some monuments there, several of them survived in Sukhothai Historical Park such as the Ta Pha Daeng shrine, Wat Phra Phai Luang, and Wat Sisawai. About some 50 kilometer north of Sukhothai is another Khmer military outpost of Si Satchanalai or Sri Sajanalaya.
In the mid-13th century, the Tai tribes led by Si Indradit rebelled against the Khmer governor at Sukhodaya and established Sukhothai as an independent Tai state and remained the center of Tai power until the end of the fourteenth century.

### Liberation from Khmer Empire (Lavo)

Prior to the 13th century, a succession of Tai kingdoms existed in the northern highlands including the Ngoenyang (centered on Chiang Saen, predecessor of Lan Na) kingdom and the Heokam (centered on Chiang Hung, modern Jinghong in China) kingdom of Tai Lue people. Sukhothai had been a trade center and part of Lawo, which was under the domination of the Khmer Empire. The migration of Tai people into the upper Chao Phraya valley was somewhat gradual.
Modern historians believe that the secession of Sukhothai (once known as Sukhodaya) from the Khmer empire began as early as 1180 during the reign of Pho Khun Sri Naw Namthom who was the ruler of Sukhothai and the peripheral city of Sri Satchanalai (modern day Si Satchanalai District in Sukhothai Province). Sukhothai had enjoyed substantial autonomy until it was re-conquered around 1180 by the Mons of Lawo under Khomsabad Khlonlampong.
Two brothers, Pho Khun Bangklanghao and Pho Khun Phameung took Sukhothai from Mon hands in 1239. Khun (ขุน) before becoming a Thai feudal title, was a Tai title for a ruler of a fortified town and its surrounding villages, together called a muang; in older usage prefixed pho (พ่อ) 'father', Comparable in sound and meaning to rural English 'paw'. Bangklanghao ruled Sukhothai as Sri Indraditya and began the Phra Ruang dynasty. He expanded his kingdom to bordering cities. At the end of his reign in 1257, the Sukhothai Kingdom covered the entire upper valley of the Chao Phraya River (then known simply as Menam, 'mother of waters', the generic Thai name for rivers.)
Traditional Thai historians considered the founding of the Sukhothai Kingdom as the beginning of the Thai nation because little was known about the kingdoms prior to Sukhothai. Modern historical studies demonstrate that Thai history began before Sukhothai. Yet the foundation of Sukhothai is still a celebrated event.

### Expansions under Ramkamhaeng

Pho Khun Ban Muang and his brother Ram Khamhaeng expanded the Sukhothai Kingdom. To the south, Ramkamhaeng subjugated the kingdoms of Supannabhum and Sri Thamnakorn (Tambralinga) and, through Tambralinga, adopted Theravada as the state religion. To the north, Ramkamhaeng put Phrae and Muang Sua (Luang Prabang) under tribute.
To the west, Ramkhamhaeng helped the Mons under Wareru (who is said to have eloped with Ramkamhaeng's daughter) to free themselves from Pagan domination and establish a kingdom at Martaban (they later moved to Pegu). So, Thai historians considered the Kingdom of Martaban a Sukhothai tributary. In practice, Sukhothai domination may not have extended that far.
With regard to culture, Ramkhamhaeng had the monks from Sri Thamnakorn propagate the Theravada religion in Sukhothai. In 1283, Ramkamhaeng is said to have invented Thai script, incorporating it into the controversial Ramkamhaeng Stele discovered by Mongkut 600 years later.
It was also during this period that the first contacts with Yuan dynasty were established and Sukhothai began sending trade missions to China. One well-known export of Sukhothai was the Sangkalok (Song dynasty pottery). This was the only period that Siam produced Chinese-styled ceramics, which fell out of use by the 14th century.

### Decline and domination of Ayutthaya

Sukhothai domination was short-lived. After the death of Ramkhamhaeng in 1298, Sukhothai's tributaries broke away. Ramkhamhaeng was succeeded by his son, Loe Thai. The vassal kingdoms, first Uttaradit in the north, then soon after the Laotian kingdoms of Luang Prabang and Vientiane (Wiangchan), liberated themselves. In 1319 the Mon state to the west broke away, and in 1321 the Lanna absorbed Tak, one of the oldest towns under the control of Sukhothai. To the south, the powerful city of Suphanburi also broke free early in the reign of Loe Thai. Thus the kingdom was quickly reduced to its former local importance only. Finally in 1378, the armies of the expanding Ayutthaya Kingdom invaded and forced Sukhothai's King Thammaracha II to yield to this new power. After the Battle of Sittaung River in 1583, King Naresuan of Phitsanulok (and crown prince of Ayutthaya) forcibly relocated people from Sukhothai and surrounding areas to the Southern Central plain, due to the war with the Burmese and an earthquake.

### Later Development

Sukhothai repopulated again but declined due to successive Burmese–Siamese wars, especially the Burmese–Siamese War (1765–67). In 1793 Rama I, after establishing Bangkok as a new capital city of the kingdom, founded New Sukhothai in Thani, 12 km (7.5 mi) to the east of old Sukhothai, thus abandoning Sukhothai. In 1801 Rama I commissioned the construction of many royal temples in the capital city. He ordered that old Buddha images be brought to Bangkok from the ruined temples around the country. One of the Buddha images is the famous eight metre (25 foot) tall bronze Phra Sri Sakyamuni (Thai: พระศรีศากยมุนี; RTGS: phra si sakkayamuni), the principal Buddha image of Wat Suthat, which was the principal Buddha image of Wat Mahathat, the biggest temple in Sukhothai. In 1833 Mongkut, during his monkhood, travelled to Sukhothai and discovered the controversial Ramkhamhaeng stele in Wat Mahathat and other artifacts, now in the National Museum in Bangkok. The formal name of this stone is The King Ram Khamhaeng Inscription Documentary heritage inscribed on the Memory of the World Register in 2003 by UNESCO.
In 1907, Vajiravudh, as crown prince, conducted a two-month archaeological field trip to Nakhon Sawan, Kampheang Phet, Sukhothai, Si Satchanalai, Uttaradit, and Pitsanulok. He later published "Phra Ruang City Journey" (Thai: เที่ยวเมืองพระร่วง; RTGS: Thiao Muang Phra Ruang) to promote historical and archaeological study by the public. The work has been used by later archaeologists and historians including Damrong Rajanubhab, the founder of the modern Thai educational system and George Coedès, a 20th-century scholar of southeast Asian archaeology and history.
In July 1988 the historical park was officially opened. On 12 December 1991, it was declared a World Heritage Site as part of the Historic Town of Sukhothai and Associated Historic Towns together with the associated historical parks in Kamphaeng Phet and Si Satchanalai.

## Management

Sukhothai Historical Park is managed by the Fine Arts Department, Ministry of Culture. The protection of the area was first announced in the Royal Gazette on 6 June 1962. The enabling law is the Act on Ancient Monuments, Antiques, Objects of Art and National Museums, B.E. 2504 (1961) as amended by Act (No. 2), B.E. 2535 (1992).

## Sights
### Wat Mahathat

Wat Mahathat or Mahathat Temple (Thai: วัดมหาธาตุ) is the most important and impressive temple in Sukhothai Historical Park. The temple's name translates to 'temple of the great relic'. The temple was founded by Sri Indraditya, between 1292 and 1347 as the main temple of the city as well as the Sukhothai Kingdom. The design is based on a mandala, representing the universe, with a principal stupa, built in 1345 to enshrine relics of the Buddha, surrounded by smaller stupas in eight directions. The main stupa has the shape of a lotus bud, which characterizes Sukhothai architectural arts. Its base is adorned with 168 stuccoed sculptings of Buddhist disciples walking with their hands clasped together in salutation. The eight smaller stupas, of which the four at the corners are in Mon Haripunchai - Lanna style and the four in between show Khmer influence. At both sides of the main stupa has two nine-metre-tall (30 ft) standing Buddha images called Phra Attharot (Thai: พระอัฏฐารส). The temple also includes an assembly hall (vihara), mandapa, ordination hall, and 200 subordinate stupas.

### Noen Prasat

Noen Prasat or Palace Hill (Thai: เนินปราสาท) is the remains of the royal palace of the Kingdom of Sukhothai. The Noen Prasat was discovered in 1833 by Mongkut, who had made a pilgrimage to the north of Siam as a monk. The palace was built on a square base with the dimensions of 200 x 200 meters. Nearby were two small ponds where the archaeologists found the remains of terracotta pipes which probably been used to supply water from a city lake to the ponds. In the southwest, there are the remains of a 1.5-meter-high (4.9 ft) brick platform on which they found ashes and bones inside, so It can be assumed that it was the royal cremation place. The Ramkhamhaeng stele was discovered here by Mongkut. He also discovered the so-called "Manangasila Throne" (Thai: พระแท่นมนังคศิลาอาสน์), an approximately 1m x 2, 50m x 15 cm large slab of gray stone, which is decorated with lotus petals depiction. The Ramkhamhaeng Stele says that Ramkhamhaeng erected this stone throne in the sugar palm grove. Mongkut took these finds to Bangkok.

### Ramkhamhaeng National Museum

Ramkhamhaeng National Museum (Thai: พิพิธภัณฑสถานแห่งชาติรามคำแหง) is a branch of the National Museum of Thailand in the Sukhothai Historical Park. It was opened in 1964 by Thailand's King Bhumibol Adulyadej and Queen Sirikit. More than 2,000 artifacts were donated from Phra Ratchaprasitthikhun, the abbot of Ratchathani Temple. Locals also contributed to the collection by donating many historical objects. Most of the objects on display in the main museum building, come from Sukhothai, others were found in Si Satchanalai, Kamphaeng Phet, Phichit and Phetchabun. The collection including Buddha images and Hindu god sculptures from Wat Phra Phai Luang and Wat Mahathat, sculptures from the pre-Sukhothai period (about 13th century), Sukhothai artifacts from the 14th and 15th centuries, early Ayutthaya artifacts from about 1351 to 1488, porcelain from the Yuan, Ming and Qing dynasties, which was found during the excavations in Sukhothai and Si Satchanalai.

### Wat Si Sawai

Wat Si Sawai or Si Sawai Temple (Thai: วัดศรีสวาย) is one of the oldest temples in Sukhothai. The temple was founded in the late-12th or early-13th century as a Hindu Shrine for Vishnu and the place for the Thiruppavai ceremony before the liberation from Lawo and foundation of Sukhothai Kingdom. The temple has three well-preserved laterite prangs, representing the Hindu trinity, enclosed by a double rampart and a moat. The lower parts of prangs are apparently Khmer, while the upper have been expanded or renovated by Thais in brick and stucco. The central prang is held in Lawo or Hindu-style. Each prang contains a cella, possibly a podium for lingam and crypt. There are few remaining stucco works on the top of central prang. Later around the 14th century the temple was adapted to the needs of the Buddhist faith: vihara were added to the south of the central prang. Numerous Chinese porcelains and Hindu god statues had been found in the area. One of artifacts is the Shiva statue discovered by Vajiravudh in 1907.

### Wat Phra Phai Luang

Wat Phra Phai Luang (Thai: วัดพระพายหลวง) was the ritual center of Sukhothai and the biggest temple in the city area. Built in the late 12th century during the reign of Jayavarman VII when the city was still under control of Khmer-Lavo. After the liberation and the construction of Wat Mahathat, Wat Phra Phai Luang lost it main ceremonial role and become Theravada Buddhist temple. Similar to Wat Si Sawai, the temple has three laterite prang, but only one still preserved in good condition. Archaeologists suspect that the three prangs originally stood on a common laterite base. All three prangs were open to the east, with doors flanked by columns which carry a richly decorated tympanum depicting scenes from the life of Buddha. The doors on the other three sides were so-called "false doors". The tympanum The complex is enclosed by double moat. The outer moat is 600 meters length and is fed by the Lam-Pan River. In the north-west of prang complex are the remains of late 14th century vihara, mandapa and a small ordination hall with eight Bai Sema. The temple is an important place to study the transition of Khmer art to Thai art. Since in the 14th century the prang has been renovated by adding elaborate stucco in leaves and frames patterns which become the basic pattern of Thai art; however, most of stucco arts are now kept at Ramkhamhaeng National Museum.$^{:17–51}$

### Wat Sa Si

Wat Sa Si (Thai: วัดสระศรี) is a small temple close to Ramkhamhaeng Monument. Wat Sa Si is beautifully situated in the midst of Traphang-Trakuan lake northwest of Wat Mahathat. Due to its location, the temple is one of the most beautiful place in Sukhothai. The temple has a Lanka styled stupa. The vihara of Wat Sa Si is situated on the east side of the stupa. Further east lies the ordination hall on its own little island. Also a large number of smaller stupas, of which today only the foundations are visible. Due to the similarities in structure and similar Bai Sema landmarks, it is believed today that Wat Sa Si were built at the same time of Wat Tra Kuan and Wat Chana Songkhram.

### Wat Asokaram

Wat Asokārām (Thai: วัดอโศการาม) or Wat Salat Dai (Thai: วัดสลัดได) was founded in the time of Sukhothai Kingdom in the reign of Sailuethai in 1399. The name of Asokaram was forgotten for a long time. Locals called the temple "Wat Salat Dai" because the terrain of Euphorbia antiquorum (Thai: สลัดได) was overgrown in the temple area. In 1958 treasure hunters dug the stupa, they found a stone inscription. Today it is on display in the Ramkhamhaeng National Museum. The stone inscription informed that Wat Asokaram was found in 1399 by the widow of Luethai, the Queen Mother, the "Satṃtec brah Rājadebī Sri Cuḷālakṣana Arrgarājamahesī Debadhòranī Tilakaratana". She was the daughter of Lithai. By her husband, Luethai they had two sons, Sailuethai, and Asoka. It is not clear why she named the temple Asokaram. One possible reason is to be a monument for her son, Asoka, other reason might have been even the name of an ancestor or even the Indian ruler Asoka. Another possibility is the name refers to "Asoka trees" Saraca asoca that are common on the temple grounds. The temple attractions are the large 5-stage step pyramid stupa, a vihara, a mandapa, and foundations of smaller pagodas.

### Wat Tra Kuan

Wat Tra Kuan (Thai: วัดตระกวน) is a small temple close to Ramkhamhaeng Monument north of Wat Mahathat. The original name of the temple is not Thai, according to a theory of Vajiravudh Tra Kuan is a Khmer term for a plant that is morning glory, a medicinal plant is used in traditional Asian medicine. Wat Tra Kuan was founded in the time of the Kingdom of Sukhothai, probably the temple was finished at the beginning of the 15th century. A majestic stupa in Lanka styled is in the west of the site. Its square base has three tier layers. East of stupa are the ruins of an ordination hall with a small terrace, six columns and a staircase on the eastern side. This layout differs from the standard Sukhothai temple, usually east of stupa should be vihara. Simple Bai Sema and the foundations of several smaller stupas are arranged around the ordination hall. In 1960s Archaeologists found a bronze Buddha image on the premises. This unique Buddha image, is now kept in the Ramkhamhaeng National Museum, resembles Lanna and Lanka styles with Sukhothai influence, thus the art historian called this style "Wat Tra Kuan style".

### Wat Chana Songkhram

Wat Chana Songkhram (Thai: วัดชนะสงคราม) is a small temple close to Ramkhamhaeng Monument north of Wat Mahathat in the same area with Wat Sa Si and Wat Tra Kuan.

### Wat Pa Mamuang

Wat Pa Mamuang or Pa Mamuang Temple (Thai: วัดป่ามะม่วง) means the mango forest monastery and was a temple of the prestigious forest monks in which the Sangharaja resided.

He built a Mandapa for the "Devalayamahaksetra", a Brahmin shrine. Although Sukhothai kings were devoted Buddhists, the royal Brahmin ceremonies was still practiced in the court. The excavations found in the 20th century that Lithai made two larger than life bronze statues of Shiva and Vishnu. The statues are now on display in the National Museum in Bangkok. In 1341 when Sukhothai adopted Ceylon Theravada Buddhism or Lankavamsa (นิกายลังกาวงศ์), Luethai invited a monk from Ceylon, Sumana Thera, to Sukhothai and resided in this temple. In 1361 Lithai appointed the famous monk Mahasamī to be Sangharaja, Mahasami had also acquired his profound knowledge of the Tipitaka during long studies in Ceylon.

### Wat Chang Rop

Wat Chang Rop (also "Rob") (Thai: วัดช้างรอบ) lies two kilometers west of Sukhothai in the wooded hills as a forest temple. In Sukhothai period the Buddhist monks could be divided according to their way of life in two groups. The first group preferred to live in monasteries within the city and focus on tripitaka study, therefore this group called "city monks" or Kamawasi (Thai: คามวาสี). The other group preferring to practice meditation and often lived in monasteries outside the city in quiet forest areas, therefore "forest monks" or Aranyawasi (Thai: อรัญญวาสี). Wat Chang Rop was one of the temples for forest monks during that time. The main structure of the temple is a bell-shaped stupa standing on a large square base.

The name of the temple means Stone Bridge Monastery, since there is a slate pathway and staircase in front of the temple complex. In various stone inscriptions found in Sukhothai, this temple was also called "Wat Aranyik", and since Wat Saphan Hin and Wat Aranyik are only about 500 meters away from each other, so perhaps originally a single temple. When Ramkhamhaeng invited a learned monk from the distant Nakhon Si Thammarat in the south of present-day Thailand to become Sangharaja of Sukhothai, he built Wat Saphan Hin with beautiful vihara for Sangharaja to reside. The temple also has a large 12.5 meters tall standing Buddha image named "Phra Attharot". Another large Buddha image was found in the mid-20th century.
