At the end of the 18th century, the owners of the hacienda were
Spanish miners formed by the Aveleira family.
In 1813 the Argentine military Francisco de Paula Otero comes to Tarma. He marries Petronila, daughter of the Aveleira and arms a small army to fight alongside General Jose de San Martin.
Once the campaign was over, Francisco de Paula Otero was appointed political-military governor of Tarma's mayoralty.
Later, Francisco de Paula Otero fights in different battles such as Junín and Ayacucho, which leads him to be named a General of Division of the Libertador Government and first prefect of Arequipa.
In 1927, the hacienda was acquired by Esteban Gandolfo Peschiera, an Italian merchant, who became famous in the local market for his activities in agriculture and livestock.

Esteban was a great friend of the famous Peruvian writer Julio Ramón Ribeyro, who used to visit the hacienda very often, thus dedicating his most famous work, Silvio en el Rosedal, to Don Esteban.

the hacienda La Florida a historic monument
José Da-Fieno Gandolfo, supported by his German wife. is the manager of the Hacienda today, dedicating it to agriculture and ecological (tourist) accommodation for travellers from all over the world.
