Aínsa

High on a promontory where the Cinca and Ara rivers meet, the walled old town is little more than two near-parallel streets running into the Plaza Mayor, with the castle's wide esplanade beyond. Aínsa was once capital of the county of Sobrarbe, and its 11th-century castle and Romanesque church of Santa María date from that time. Today it is a base for canyoning, rafting and Pyrenean walks.

Highlights
