Castle of Querol Monument · Querol, Alt Camp, Tarragona Castle on a crag near the valley of the Gaià river, in the municipality of Querol (Alt Camp, Tarragona), at 575 metres above sea level. Romanesque in style with late Gothic elements, it preserves a circular tower some 4 metres high, with walls 80 to 120 centimetres thick, and a rectangular enclosure of about 35 by 20 metres with two chambers with pointed arches and vaults. Its walls show three phases: a base of irregular ashlars, a Romanesque band with arrow slits, and an upper section with larger openings and battlements. Occupied in the 10th century by Ansulf de Gurb, it passed between 1018 and 1112 to the Cervelló family, feudal vassals of the counts of Barcelona; between 1528 and 1597 it came by marriage to the Sayol family. Destroyed in 1835 during the First Carlist War. A cultural asset of national interest. Photo: Angela Llop (CC BY-SA 2.0) What to see and do in Querol
