Castle of Fuentidueña de Tajo

Fuentidueña de Tajo, Spain, Spain

---

The Castillo de Fuentidueña de Tajo is a 12th-century medieval fortress dramatically perched on a hill overlooking the town and Tagus River in Fuentidueña de Tajo, Community of Madrid, Spain.

Expanded and rebuilt in the 14th century with links to kings Alfonso VI and VIII, it features an irregular layout including surviving walls, cylindrical side towers, an interior moat dividing its sections, and a prominent Homage Tower facing the town.

Associated with historical figures like Queen Urraca—who legend says wandered its hidden corridors—and later nobles such as Pedro Manrique and Álvaro de Luna, the castle served as a strategic headquarters during turbulent times of the Reconquista and feudal power struggles.
