The Castillo de Villora crowns a hilltop dominating the mountain town of Villora in Cuenca's Lower Serranía, constructed in the 12th century during the Andalusí period as a minor surveillance fortification. This albarrana tower-castle of Arab design comprised four stories with lime and stone walls reinforced by ashlar stone at corners, featuring Gothic additions from its Christian period reuse. During the First Carlist War in 1840, Carlist troops set the fortress ablaze as punishment for Villora's resistance to their cause. Though progressively ruined, the main tower and fortification remnants survive with free public access via a footpath ascending from the town center through historic streets.
