Then there is the Gothic palace of Peter IV, dating from the same century, an excellent example of Gothic palace architecture, unique in Aragon. Santa María Church is a designated Cultural Property, with its cloister and Romanesque/Gothic decoration. San Juan Church is also designated Cultural Property and has 13th century murals.
