Monastery of San Zoilo

Originally dedicated to John the Baptist, it obtained its current name after receiving the relics of Saint Zoilus in 1047.

In 1118, Queen Urraca donated to it the church of San Martín de Frómista.

King Ferdinand III exempted the citizens from royal taxes, directing them to pay the monastery instead.

It was abandoned during the Spanish confiscations in the 19th century, before being acquired by the Jesuits and turned into a school.

It contains a monumental depiction of King Louis IX of France and the coats of arms of some of the abbots.
