Castle of Castelltort Monument · Guixers, Solsonès, Lleida Castelltort is one of the seven population entities of the municipality of Guixers, in the Solsonès, located in the south of the municipal term. Like the other entities of Guixers, its origin goes back to the old ecclesiastical division into parishes; that of Sant Climent de Castelltort still retains that category. Formerly the parish stood beside the castle of the same name, on the slope of a hill facing the present-day parish, on the other side of the Llosa del Cavall reservoir, the highest of the three that make up the Aiguadevalls range. Of the 11th-century castle there remain today wall remains of two enclosures and of the old Romanesque church of Sant Climent, accessible only when the reservoir's water level drops enough to use the old access path.
