The monastery of San Pedro de Siresa is a beautiful Romanesque-style monastery located in the town of Siresa (two kilometers from the town of Hecho). It is the oldest monastery in Aragon. There are guided tours of the monastery... and it is well worth it.

If you are interested in visiting the parish church, dedicated to San Pedro, you can try to contact the family that lives behind, who keep the key and used to show it with pleasure if they had time.

Arrés is a pretty town located on a promontory in the province of Huesca. It preserves the ruins of a fifteenth-century Gothic castle, now restored. It is part of the Aragonese Way and therefore has a pilgrim hostel and a restaurant.
