Castle of Riner Monument · Riner, Solsonès, Lleida The Castell de Riner is a fortified tower from the 12th-13th centuries in the municipality of Riner, in the Solsonès, declared a Bien Cultural de Interés Nacional (Spain's highest level of heritage protection). It stands halfway up a slope above the riera de Cardona, next to an area of fields, in a strategic position. The site is documented since 997 and the castle since 1013, linked to the Riner and Sal·la de Conflent families; in 1142 a dispute over its ownership was settled between the lord Ponç de Cervera and the castellan Pere de Riner, and in 1322 Bernat de Riner paid homage to the parish priest of Solsona. Rectangular in plan, it preserves a tower about 18 metres high with walls 2 metres thick, a nave covered by a pointed vault, and an ashlar doorway with a semicircular arch.
