Castle of Ainsa

Ainsa Castle is in the old city, next to Plaza Mayor. It's the first thing you see when you go up to the top of the city, looking over all the old medieval town. The castle is home to the Celtic music and "Ainsa Castle" folk festival. It's also celebrated in the esplanade of the castle, the Expoferia Sobarbe. Besides a large patio and walls, you can find a tourist office and a small eco-museum.
