San Esteban de Gormaz
During the Christian reconquest the ancient Roman baths were converted into a royal palace. King Ordoño II, who had occupied the throne of Leon in 916, defeated the Arabs in the Battle of San Esteban de Gormaz in 917. As a sign of gratitude to God for victory, he gave up his palace to build the first cathedral. Under the episcopate of Fruminio II, the building was transformed into a sacred place. The tomb of Ordoño II of Leon, who died in 924, is found in the cathedral.
