The colonial history of Lima officially began in 1535, when Francisco Pizarro founded the city, declared that the Plaza Mayor was the main square and placed the first stone of the cathedral on the same day. Anyone who founds a city and a ruler in a city can also grant land. An example that still exists is the Casa de Aliaga. In the year of foundation of 1535, Pizarro gave his deserving defender Don Jerónimo de Aliaga, one of the first settlers in Lima, a piece of land next to the palace, which he himself built and is now the palace of government in the Main Square. The house was built in the same year and is located, as well as the Government Palace, on the remains of a Huaca, a Taulichusco sanctuary, the chief who ruled the Rimac Valley before the arrival of the Spaniards. Thus, Casa de Aliaga is as old as the city of Lima itself, and it is said to be the oldest house in South America, still inhabited by the family that once built it. The Aliagas have lived there for 17 generations. For centuries, it has been damaged and renovated several times during earthquakes, resulting in a mixture of different architectural styles.
