The monastery building still has many of its original features despite the various architectural alterations it has undergone since the 18th century. One of those elements is the Renaissance-style inner cloister. This was the first university and the secondary school in the Canary Islands for a long time, with such distinguished alumni as Benito Pérez Galdós, Óscar Domínguez and Juan Negrín. All that remains of the church are its ruins since it was consumed by a fire in 1964. The original rectangular structure is best seen from the outside, with three naves separated by Roman arches.
