Joaquín Toesca

Gioacchino Toesca e Ricci (1745–1799; known as Joaquín Toesca in the Spanish Empire) was an Italian architect who worked at the service of the Spanish Empire, mainly in Chile.

In 1780 he traveled to South America, to Santiago in the colonial Captaincy General of Chile at the request of the Royal Governor Agustín de Jáuregui and the Archbishop Santiago Manuel de Alday y Aspée, who engaged him to design the Catedral de Santiago de Chile (present day Santiago Metropolitan Cathedral).

[1] In addition to this project he was also occupied in developing the plans for the Palacio de la Moneda to house the royal mint, which later became Chile's presidential palace.

Toesca died in 1799 and did not live to see his two major projects, the Cathedral and the Palacio, completed.

However, he did finish a number of other smaller works, including the Cabildo de Santiago (city hall) of the Santiago Cabildo, the San Juan de Dios Hospital, and the tajamares (levees) which would prove crucial in protecting the city from the floods of the Mapocho River.
