Castillo de Torresaviñán is a medieval defensive complex in Torremocha del Campo, Guadalajara, built in the 12th century by Don Manrique de Lara using an ancient Muslim tower as its foundation. The fortress served to protect the western boundary of Lara's lordship against rival fortresses and formed part of a broader defensive line through the region, reinforced in the 14th century and reformed in the 15th. The castle's defining feature is its square tower, rising approximately sixteen meters and built with deliberately rough, purely defensive finishes unsuitable for comfortable habitation. Austrian armies destroyed much of the structure during the War of Spanish Succession, explaining the castle's current ruinous state, though it remains protected under Spanish cultural heritage law.
