Huesca - San Pedro el Viejo

The Monasterio de San Pedro el Viejo ("Saint Peter the Old") is a former Benedictine monastery built within the 12th century. A church had existed here (built on the place of a Roman temple) since Visigothic times and even, when the Moors hold Huesca, this church was in use.

Christian troops conquered Huesca in 1096 and from 1117 on Benedictines with obvious ties to Cluny reconstructed the church and erected a monasterio here.
Of course the Benedictian monastery needed a decent cloister. This got erected adjoining the church around 1140. Many of the capitals, carved in the style of the "Master of Agüero" (aka "Master of San Juan de la Peña"), are creations done during the renovation of San Pedro el Viejo end of the 19th century.

This capital is (probably) one of the old (original) ones. A centaur attacks a mermaid with bow and arrow. The mermaid holds two large fishes. Maybe the centaur is a mugger...
