The Basilica del Pilar is the jewel of baroque art in Aragón. It stands on the banks of the Ebro in the place previously a Gothic church was built in 1515 and formerly a Roman temple of 1434. Inside the basilica stands the Holy Chapel of Ventura Rodríguez containing the image of the Virgin of Pilar. Also interesting are the Altarpiece, made entirely of alabaster, and the Renaissance choir. They also highlight very important frescoes by Francisco de Goya.
