Torre Sasiola

Deba, Gipuzkoa, Spain, Spain

---

Torre Sasiola in Deba, Gipuzkoa province, Basque Country, Spain, is a 15th-century medieval tower house built by the powerful Sasiola family—one of Deba's most prominent lineages during the Middle Ages—as both a fortress and residence.

Featuring a rectangular limestone ashlar plan with a four-sided roof, it retains defensive elements like robust walls despite major 1865 reconstruction after a devastating fire, including machicolations and arrow slits typical of Basque montañesa architecture.

Notable descendants include Martín Ochoa de Sasiola, treasurer to Castile's Constable, Jofre Ibáñez de Sasiola, Castile's first ambassador to England, and poet María Estibaliz de Sasiola; today it serves as private housing within a protected historic context near the Franciscan Convent of Sasiola.
