Old Monastery of San Juan de la Peña
Highlight • Religious Site
Tickets are available online (here: articketing.vocces.com/) but tickets that have not been sold online for that day are also sold at the box office (right at the door).
When I was there, the person at the ticket office lent himself to keep me and watch my bike while I went in to visit him.
Needless to say, it is worth it because it is impressive how the construction is integrated into the rock.
In addition to the Camino de Santiago, it is also a fundamental crossing point on the Route of the Holy Grail, as it is said that the monastery housed it between 1071 and 1399.

Loarre Castle or Loarre Abbey Castle (in Aragonese castiello de Lobarre) is a Romanesque castle located in the province of Huesca, Aragon, Spain. It was built in the 11th century and is in a good state of preservation, making it one of the best examples of Romanesque military and civil architecture in Spain. The castle sits on a limestone promontory that it uses as a foundation. This was a great defensive advantage, since the walls could not be mined (a common technique in the siege of fortresses, which consisted of building a tunnel under the wall and then collapsing it to open a breach through which to attack). It is also surrounded by a wall with towers. The castle is in a fairly good state of preservation (except for the part of the old castle of Sancho III of Navarre, which is much more deteriorated) and is considered the best preserved Romanesque fortress in Europe.
