At the time of its construction in 1630, during the reign of Philip II of Portugal, the land belonged to Archbishop Aleixo de Meneses. The Commandery of the Military Order of Military Order of St. Benedict of Aviz had used the convent as a meetinghouse. Later in 1643, the Brothers of the Slaves of the Blessed Sacrament began operating in the convent church. In 1734, it suffered from a fire. The nuns relocated to the St. Anthony convent following the Earthquake of 1755, which destroyed parts of the building but returned in 1758 after the restoration was completed.

After the expulsion of religious orders in 1834, it was occupied by the Honorary Commanders of the Order of Avis until the establishment of the Portuguese Republic October 5, 1910.
