Now occupied by the GNR Training Center. Its architectural and sculptural heritage is important (National Monument, 1910) namely for its two cloisters, with a chapter room, and for the portal of the church and the tomb of the founder, sculpted in marble and attributed to Nicolau de Chanterenne.
D. Jorge de Melo (1572-1548), the last Bishop of Guarda, who ruled the huge diocese from this city until it split, creating the Portalegre autonomous one, he is buried in the huge tomb, with a lying statue .
He received from Philip I, in 1581, a comment as witty as it was accurate: a large cage for a small bird. This is, without a doubt, one of the jewels of the city's heritage that awaits its deserved appreciation.
