Castillo de Siero

Spain, Spain

---

The Castillo de Siero refers to remnants of medieval towers integrated into historic manor houses in Siero municipality, Asturias, Spain, such as the 14th-century Torre de Celles within the Palacio de la Torre de Celles.

This defensive structure, part of a larger Baroque palace complex from the 17th century with four corner towers, Tuscan columns, ornate south facade, and a central courtyard, originated under noble families like the Andrades granted by Charles I, evolving through phases including a medieval northwest tower and later expansions.

Recognized as a cultural heritage site, it exemplifies Asturian rural nobility architecture blending military and residential elements, though not a standalone castle and with limited public access.
