La Seo

Dominating the eastern end of Plaza del Pilar is the Catedral de San Salvador, more popularly known as La Seo.

La Seo may lack the fame of the Basílica de Nuestra Señora del Pilar, but its interior is easily its architectural superior. Built between the 12th and 17th centuries, it displays a fabulous spread of architectural styles from Romanesque to baroque. It stands on the site of Islamic Zaragoza's main mosque (which in turn stood upon the temple of the Roman forum). The northwest facade is a Mudéjar masterpiece, deploying classic dark brickwork and colourful ceramic decoration in eye-pleasing geometric patterns. All the chapels are framed by beautiful stonework and ring the changes from the eerie solemnity of the Capilla de San Marcos to the glorious Renaissance facade of the central Christ Chapel and the exquisite 15th-century high altarpiece in polychrome alabaster.

The admission price includes entry to La Seo's Museo de Tapices, which has an impressive collection of 14th- to 17th-century Flemish and French tapestries.
