The Reliquaries
Following a rule approved by the Council of Trent dealing with the veneration of saints, Philip II donated to the monastery one of the largest reliquaries in all of Catholicism. The collection consists of some 7500 relics, which are stored in 570 sculpted reliquaries designed by Juan de Herrera. Most of them were constructed by the artisan, Juan de Arfe Villafañe. These reliquaries are found in highly varied forms (heads, arms, pyramidal cases, coffers, etc.) and are distributed throughout the monastery, with the most important being concentrated in the basilica.
