It retains its twin doorways, typical of female convents.

Notable features include two marble reliefs depicting the Annunciation and the Martyrdom of Saint Lawrence. 

To the left, towards República de Argentina, there is an extension of the former convent of Santa María de la Encarnación, founded in 1594 by Receptorist nuns. The convent and the church were built between 1639 and 1648, although in the 18th century, it underwent significant repairs by the architect Miguel Constanzó. 

After the nuns were expelled in the 19th century, the building served various purposes until it was assigned to the Ministry of Public Education after the success of the Revolution, a purpose it still serves today. 

The interior of the property consists of two courtyards with three floors where Diego Rivera painted 1,585 square meters of murals using the fresco technique between 1923 and 1928. These murals form one of the most complete sets of mural painting and are based on themes suggested by José Vasconcelos, who was the Minister of Education during those years.
