Watchtower of Segurilla Monument · Segurilla, Sierra de San Vicente, Toledo Image of Segurilla, not of the place itself. The watchtower of Segurilla stands at the highest point of a hill, at 623 metres above sea level, with views over the Tajo and Alberche basins, the Montes de Toledo, the Sierra de Gredos and the Sierra de San Vicente. Built around the year 937, already in the 10th century, during the caliphate of Abd al-Rahman III, it formed part of the watch network of the Marca Media, the frontier centred on Toledo, with functions of warning against threats and containing the enemy's first attack. It is a circular Islamic tower, about 18 metres high, built of rubble masonry and lime, on which the putlog holes from the scaffolding can still be seen; its access door, located several metres above the ground, was reached by a wooden or rope ladder. At its foot, on 27 July 1809, the Battle of Talavera was fought, in which the French army was defeated by the Anglo-Spanish forces.
