This 15th-century Gothic monastery was once the headquarters of the Inquisition in Avila. For 3 centuries, it housed the tomb of Torquemada, the first general inquisitor, whose zeal in organizing the Inquisition made him a notorious figure in Spanish history. Legend has it that after the friars were expelled from the monastery in 1836, a mob of Torquemada-haters ransacked the tomb and burned the remains somewhere outside the city walls. His final burial site is unknown.

Prince John, the only son of Ferdinand and Isabella, was also buried here, in a sumptuous sepulcher in the church transept. The tomb was desecrated during a French invasion; now, only an empty crypt remains.

Visit the Royal Cloisters, in some respects the most interesting architectural feature of the place. In the upper part of the third cloister, you'll find the Museum of Far Eastern Art, which exhibits Vietnamese, Chinese, and Japanese art and handicrafts.
