The seminary founded in the 16C by Archbishop Juan de Ribeira now houses a museum. As well as a wonderful 14C Byzantine cross, works by Juan de Juanes, the precious Tryptych of the Passion by Thierry 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: the work is typical of the Italian Matarrana.
