The Palace of the Castejón Family Monument · Ágreda, Moncayo, Soria Image of Ágreda, not of the place itself. The Castejón Palace is the most important building of civil architecture in Ágreda, built in the early 17th century. It has a sober portal topped by a broken pediment with a coat of arms at its centre, a harmonious courtyard and a square rubble-stone tower with watchtowers. It preserves the Renaissance garden of don Diego de Castejón, a landscaped space uncommon in Soria's civil architecture and today open to the public alongside the palace.
