Castillo de Arevalo

Arévalo, Spain, Spain

---

Castillo de Arévalo is a 15th-century fortress in Arévalo, Ávila province, Spain, originally built with mudéjar influences and later reformed in the 16th century by the Catholic Monarchs into a pentagonal artillery bastion featuring brickwork, a massive Tower of Homage, and Italian-style battlements.

Once a state prison holding nobles like Prince William of Orange, it later served as a cemetery and grain silo before restoration in the 1950s by Spain's Ministry of Agriculture. Today, this well-preserved monument houses a permanent exhibition on the castle's history and local grain storage innovations.
