Castillo de Serranos de la Torre, commissioned by Bishop Lope de Barrientos in 1451 in Zapardiel de la Cañada, Ávila, exemplifies 15th-century Castilian fortress architecture with its granite ashlar masonry, square keep, low perimeter walls, and two large angular bastions. The castle features intricate details including a chimney, loopholes, splayed windows, and an entrance bearing an episcopal shield. Though now progressively ruined and used for agricultural purposes, this 1949-designated Cultural Heritage site reflects the ambitious building programs of powerful ecclesiastical lords during the early reign of the Catholic Monarchs in Castile.
