The former Corpus Christi seminary, founded in the 16C by Archbishop Juan de Ribera, now houses a museum. As well as a wonderful Byzantine cross, works by Juan de Juanes, the precious Triptych of the Passion by Dirck Bouts, and paintings by Ribalta, Morales and El Greco are also on show. The church is also worth a detour and is one of the rare examples in Spain of a Renaissance sanctuary decorated with frescoes.
