Castle of l'Albiol Monument · l'Albiol, Baix Camp, Tarragona The castle of l'Albiol, a border castle that gives the municipality its name, stands in ruins on a hill at about 866.5 metres of altitude. It was of large proportions, and stretches of wall still survive with some half-collapsed square towers and the central buildings. A castle of Saracen origin, it was taken by Guillem de Claramunt shortly before the conquest of Siurana; in 1158 Count Ramon Berenguer IV ceded it to Joan de Martorell with the charge of rebuilding it, and he in turn passed it on to the archbishopric of Tarragona. It was torn down by order of the Castilian troops in 1654, during the War of the Reapers, with only a small part surviving since then; the construction of the present parish church of Sant Miquel probably dates from that same period.
