Museo Diocesano de Jaca
Housed inside Jaca's 11th-century cathedral — the oldest Romanesque cathedral in Spain — the Diocesan Museum holds a collection of medieval frescoes and carved capitals so vivid they feel freshly painted. This is not a dusty archive; it is a masterclass in the art that once lined the pilgrimage road to Santiago.
Spain's oldest Romanesque cathedral
The Catedral de San Pedro, begun around 1063 under King Sancho Ramírez, set the architectural template for dozens of churches along the Camino de Santiago. Its carved south portal, with the distinctive chrismon symbol, is one of the earliest dated examples of Romanesque sculpture on the Iberian Peninsula.
Step inside and the three-aisled nave feels surprisingly light, its columns topped with capitals carved with biblical scenes, fantastical beasts and knotwork that medieval pilgrims would have read like an illustrated Bible.
Frescoes rescued from mountain villages
The museum's greatest treasure is its collection of Romanesque frescoes transferred from remote Pyrenean churches — a rescue operation carried out in the 20th century to save them from damp and neglect. The apse paintings from San Juan de Busa and the panels from Bagüés are among the finest surviving examples of 11th- and 12th-century Spanish religious painting.
Displayed in reconstructed apse settings, the frescoes glow with ochre, cobalt and crimson pigments that have barely faded in nine centuries. Allow at least 90 minutes — this collection rivals anything in Barcelona's MNAC for sheer medieval drama.
