For the curious reader

History, landscape and context.

Colonia del Sacramento is a city in southwestern Uruguay, by the Río de la Plata, facing Buenos Aires, Argentina. It is one of the oldest towns in Uruguay and the capital of the Colonia Department. As of the 2023 census, it has a population of around 32,174. Following the restoration of the Portuguese crown, King Peter II sought to establish the southern border of Brazil. Manuel Lobo with 5 ships containing about 400 soldiers, craftsmen, carpenters and stonecutters, and 18 guns, reached San Gabriel Island on 20 January 1680.
