Hill of the Virgen del Castillo Monument · Bernardos, Comunidad de Ciudad y Tierra de Segovia, Segovia About three kilometres from the village of Bernardos, on the left bank of the Eresma river, this hillfort site preserves a fortified settlement inhabited from the 5th to the 11th century. It has a double defensive enclosure: the outer one, larger, with semicircular bastions, surrounds a narrower inner enclosure that protected the most vulnerable part of the settlement. The walls, about two metres wide on average, were built with slabs of slate, quartzite and schist bonded with lime and sand mortar. On the north flank a gate 3.20 metres wide opens between two towers. Inside the inner enclosure stands the ermita de la Virgen del Castillo, patroness of the municipality, with an annual romería; the site was declared a Bien de Interés Cultural (Spain's highest level of heritage protection) on 12 May 2005.
