In 1891, fostered by the encyclical Rerum Novarum of Pope Leon XIII that called on taking social consciousness of the workers and solving difficulties regarding their life conditions, the construction started per stages of one of the first social housing projects of the country in Santiago.

The first stage that was inaugurated on November 21, 1891, and it was possible thanks to the contributions of Melchor Concha y Toro, old minister of the Treasury of the government of President José Joaquín Pérez and that had began investing in the wine growing business bringing French grape stock from Bordeaux for the floor plans in the Valley of the Maipo River, starting the Concha y Toro Vineyard. Afterwards, the housing project was extended thanks to the contributions of the beneficiaries Manuel José Irarrázaval and Eduardo Marín.

In 1916, celebrating the 25 years of the Institution León XIII, the Epiphany of the Lord Parish is inaugurated on June 25, built to commemorate the anniversary, with a mass in charge of the Chaplin Carlos Casanueva.

In the Parish Yard and along with the celebration of the 25 years of the housing project León XIII a bust of Melchor Concha y Toro was placed in appreciation for his support in the creation of the housing project with a plate that, along with the recognition of the benefactors, that reads: “Homage in gratitude by the housing project León XIII to its founder Mr. Melchor Concha y Toro”.

In 1997, under the continuous petitions of the people of the housing project of the zone, the neighborhood was declared Typical Zone and its National Parish Monument, mainly due to its social importance within the downtown area of Santiago in housing history and for maintaining its original form and keepsake of a typology of the Chapel of the “European French Campaign”.

Today, after the earthquakes occurring in 1985 and 2010, the Parish has had restoration and embellishment works, but unfortunately it has been affected by looting. It is working and the homage bust can be appreciated in its lateral yard.
