Cathedral of San Pedro de Jaca Monument · Jaca, La Jacetania, Huesca The cathedral of San Pedro de Jaca, seat of the diocese of the same name, is one of the oldest and most characteristic Romanesque buildings in Spain: construction began almost at the same time as the cathedral of Santiago de Compostela, in the last quarter of the 11th century, on the initiative of King Sancho Ramírez, who in 1068 had placed his kingdom under vassalage to the pope and obtained in exchange the episcopal see for Jaca. The city received its city fuero from Sancho Ramírez himself in 1077 and was the capital of the Kingdom of Aragon until 1096, when, after the conquest of Huesca, that city regained its former status as capital. The cathedral's construction, whose architect is unknown, took place in two stages, between 1077 and 1082 and between 1104 and 1130, and it served as a model for other churches on the Camino de Santiago.
