Jaca - Catedral de San Pedro

The Jaca Cathedral is one of the oldest of the Iberian peninsula, dating back to the 1070s. The building, that was altered many times later, was commissioned by King Sancho Ramírez, who established an episcopal seat in Jaca, then the capital of the Kingdom of Aragon.

The Romanesque cathedral was completed around 1130. In 1395 a blaze destroyed large parts of the cathedral. The ceiling had to be reconstructed in the following decades and got renovated in the 16th century, when the aisles were added and the nave got enlarged.

I am not sure, when a cloister was added to the cathedral, seen in the background. Today this cloister, erected around this green square, hosts the Cathedral´s Museum ("Museo Diocesano de Jaca").
