Jaca is a city lying at the foot of the Pyrenees and an important stop on the pilgrim route to Santiago de Compostela. There is a powerful 16th century citadel that used to defend the passage through the Pyrenees.
From the early Middle Ages, the settlement, and later the castle at the site of today's Jacy, had a very important strategic importance because it allowed the control of a convenient route leading through the Pyrenees. It was here that the first victory over the Moors, which started the Reconquista's triumphal procession, was achieved.
In the 11th century, a Romanesque cathedral dedicated to St. Peter. It is the most important monument in the city and despite the reconstructions, it has been largely preserved in its original appearance. Inside one of the apses you can see frescoes from the end of the 18th century.
In order to finally secure the passage through the Pyrenees, the Jaca Citadel was built in the 16th century. It is a bastion building on a star plan, surrounded by a moat. It has been preserved practically unchanged. One of the buildings houses the Museum of Military Miniatures, which presents miniature reconstructions of battles important to the history of the world.
