To the left of the entrance is a baptismal font. It was used in 1195 to baptise Saint Anthony, who was born nearby at the spot where a church now bears his name. His life is chronicled in the neighbouring museum. The nave is covered by barrel vaulting and has an upper, arched gallery. Light flows in through the rose window on the West façade and transept. Arches extend up to the vaulted ceilings while medieval statues and decorative altars fill the alcoves. Within the seventh chapel, the Capela de Santo Ildefonso, are three Gothic tombs, the most striking of which is the beautifully sculpted sepulchre of Lopo Fernandes Pacheco with his hand on his sword and his faithful hound sat at his feet. The tomb of Maria de Vilalobos is sculpted with her reading a Book of Hours whilst her dog is busy eating a chicken. Daily: 07h00 - 19h00 | Entrance: FREE
Later toward the end of the 13th century, King Dinis ordered the construction of the Gothic cloisters. A curious oculus located over one pair of arches takes the form of a pentagram and heart pattern within its tracery. It is thought to be a Templar symbol. Since 1990 excavations in the courtyard of the cloisters have unearned finds from the Roman, Arab and mediaeval periods. Archaeologists have found a Roman street with shops on either side. Remnants of later habitats dating from the Visigoth period have also been discovered here. A part of a Moorish building, with red walls, are remnants of a former mosque, has also been excavated here. A large portion of the cloisters was severely damaged during the 1755 earthquake.

A small museum and treasury can be reached via a ticket man and up a flight of stairs where a hoard of ecclesiastical objects can be found.

Other artefacts include intricately embroidered ecclesiastical costumes, manuscripts, stunning statues and antique silver. Monday – Saturday: 10h00 - 17h00, Sunday: Closed | Entrance: €2.50
