The Seo, or cathedral of Zaragoza, encompasses a range of architectural styles from Romanesque to Churriguresque, but it is the Gothic style which dominates here. Five naves of equal height lend an impressive appearance to this interior. The Gothic altarpiece above the high altar is striking, as is the 15C Moorish style cupola. The cathedral boasts an exceptional collection of Gothic tapestries, which are exhibited in rotation in the Museo de Tapices.
