Cerro del Castillo · Ayllón

At the top of Cerro del Castillo stands La Martina, the pentagonal watchtower that has become the emblem of Ayllón. Built in the eighth century during the Arab occupation, it was part of the defensive wall of the town, of which there are still remains known as Los Paredones. After the reconquest, it was integrated as the bell tower of the church of San Martín, from which it takes its name. Although the parish church was abandoned in the 18th century, the tower continued to mark the days of the farmers with its bells, and is today a historical and patrimonial symbol of the town.
