This quaint hamlet, a few kilometers from Huesca and on the banks of the Isuela River, is nestled in the southern part of the region.
Points of historical interest include the hamlet’s medieval Chapel of Santa Ana. This Romanesque-style church from the late 12th or early 13th century features a single nave that was made taller in ensuing centuries.
The name (“Castillo” means castle) does not refer to a past defensive role of the hamlet, but rather to the region’s agricultural past: in Alto Aragón, this place-name is customarily applied to isolated farms.
