Few data have been collected about this Jesuit school in Ourense. As great part of the ones created in Galicia, it was made on the Indians' initiative or contribution. This school counted on the donative assessed on 2000 ducats that an old student of the School of Monterrey gave in 1621 for the construction of a new Jesuit school in Ourense. However, it was not carried out until 1653 or 1667 depending on the sources consulted. Since the donation until its construction, priests settled in the Palace of the Oca Valladares. A temple was built in the 18th century next to the school. The church, which presented a Baroque façade, was named Santa Eufemia. After the Jesuits' expulsion, the original parish, also named Santa Eufemia but located elsewhere, was transferred to the Jesuit temple. The school changed its owners in the 18th century due to some economic complications. Thus, they started to depend on the Counts of Maceda. In 1767, after Charles III's Decree of expulsion, the school became inoperative. It counted on two Grammar teachers then.
