Some context: Benjamin Henry Boneval Latrobe (May 1, 1764 - September 3, 1820) was a British subject and neoclassical architect who emigrated to the United States. He was one of the first formally trained, professional architects in the new United States, drawing on influences from his travels in Italy, as well as British and French Neoclassical architects such as Claude Nicolas Ledoux. In his thirties, he emigrated to the new United States and designed the United States Capitol, on "Capitol Hill" in Washington, D.C., as well as the Old Baltimore Cathedral or The Baltimore Basilica, (later renamed the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary). It is the first Roman Catholic Cathedral constructed in the United States.
Latrobe returned to England in 1784, and was apprenticed to John Smeaton, an engineer known for designing Eddystone Lighthouse. Then in 1787 or 1788, he worked in the office of neoclassical architect Samuel Pepys Cockerell for a brief time. In 1790, Latrobe was appointed Surveyor of the Public Offices in London, and established his own private practice in 1791. Latrobe was commissioned in 1792 to design Hammerwood Park, near East Grinstead in Sussex, his first independent work, and he designed nearby Ashdown House in 1793. Latrobe was involved in construction of the Basingstoke Canal in Surrey, together with engineers John Smeaton and William Jessop. In spring 1793, Latrobe was hired to plan improvements to the River Blackwater from Maldon to Beeleigh, so that the port of Maldon could compete with the Chelmer and Blackwater Navigation, which bypassed the town. The project lasted until early 1795, when Parliament denied approval of his plan. Latrobe had problems getting payment for his work on the project, and faced bankruptcy. In February 1790, Latrobe married Lydia Sellon, and they lived a busy social life in London. The couple had a daughter (Lydia Sellon Latrobe) and a son (Henry Sellon Boneval Latrobe), before she died giving birth during November 1793. Lydia had inherited her father's wealth, which in turn was to be left to the children through a trust with the children's uncles, but never ended up going to the children. In 1795, Latrobe suffered a breakdown and decided to emigrate to America, departing on November 25 aboard the Eliza. In America, Latrobe was known for his series of topological and landscape watercolors; the series started with a view of the White Cliffs of the south coast of England viewed from the Eliza. The series was preceded by a watercolor of East Grinstead, dated September 8, 1795.

Some context: The overseas expansion under the crown of Castile was initiated under the royal authority and first accomplished by the Spanish conquistadores. The Americas were incorporated into the Spanish Empire, with the exception of Brazil and Canada, and the crown created civil and religious structures to administer the region. The motivations for colonial expansion were trade and the spread of the Catholic faith through indigenous conversions. Beginning with the 1492 arrival of Christopher Columbus in the Caribbean and continuing control of vast territory for over three centuries, the Spanish Empire would expand across the Caribbean Islands, half of South America, most of Central America and much of North America (including present day Mexico, Florida and the Southwestern and Pacific Coastal regions of the United States).
During the Napoleonic Peninsular War in Europe between France and Spain, assemblies called juntas were established to rule in the name of Ferdinand VII of Spain. The Libertadores (Spanish and Portuguese for "Liberators") were the principal leaders of the Spanish American wars of independence. They were predominantly criollos (Americas-born people of European ancestry, mostly Spanish or Portuguese), bourgeois and influenced by liberalism and in some cases with military training in the mother country. In 1809 the first declarations of independence from Spanish rule occurred in the Viceroyalty of New Granada. The first two were in present-day Bolivia at Sucre (May 25), and La Paz (July 16); and the third in present-day Ecuador at Quito (August 10). In 1810 Mexico declared independence, with the Mexican War of Independence following for over a decade. In 1821 Treaty of Cordoba established Mexican independence from Spain and concluded the War. The Plan of Iguala was part of the peace treaty to establish a constitutional foundation for an independent Mexico. These began a movement for colonial independence that spread to Spain's other colonies in the Americas. The ideas from the French and the American Revolution influenced the efforts. All of the colonies, except Cuba and Puerto Rico, attained independence by the 1820s. The British Empire offered support, wanting to end the Spanish monopoly on trade with its colonies in the Americas. In 1898, the United States achieved victory in the Spanish-American War with Spain, ending the Spanish colonial era. Spanish possession and rule of its remaining colonies in the Americas ended in that year with its sovereignty transferred to the United States. The United States took occupation of Cuba, the Philippines, and Puerto Rico. Puerto Rico continues to be a possession of the United States, now officially continues as a self-governing unincorporated territory.
