It is the oldest of the seats currently occupied by the university and one of the most important non-religious historical buildings in the city of Lima.

The history of the building begins in 1605, when the wealthy Spaniard Antonio Correa Ureña granted an important donation for the construction of a novitiate built to educate and train the new members of the Society of Jesus.

[2] In 1767 three years after the expulsion of the Jesuit order, Viceroy of Peru Manuel de Amat y Junyent founded the Real Convictorio de San Carlos, a type of university, in the former ecclesiastical building, in honour of King Charles III of Spain.

[citation needed] In 1989, the National University of San Marcos, the Spanish Agency for International Development Cooperation and the National Institute of Culture signed a cooperation agreement to restore the architectural set and to be dedicated to culture, research and artistic creations.

[citation needed] Its vault has thirteen beautiful paintings from the mid-18th century,[3] inspired by saints and doctors of the Church like St. Augustine, St. Thomas Aquinas and others.

In this room of debates and controversies, the most important ceremonies of the University are currently held, such as graduations, solemn sessions and seminars.

The Law Faculty worked in the Courtyard los Maestros, which is the main one and has in the center a carved sculpture, mute witness to innumerable historical events and symbol of the University that appears in the current bills of 20 nuevos soles.

One of its former curators includes the late Rebeca Carrión Cachot, a Peruvian archaeologist, historian and teacher who studied under the aforementioned Tello.
