Castell de Castelló de Farfanya crowns a hilltop in Castelló de Farfanya village, Noguera comarca, Lleida province, Catalonia, Spain, originating as a 9th-century Muslim fortress (Thagr al-Ala) forming part of al-Andalus's defensive chain against Christian advances.

Conquered around 1115-1116 by viscount Guerau II de Cabrera during the Reconquista, it was remodeled for feudal use with a trapezoidal eastern service area, reinforced 1.9-meter-thick walls using irregular masonry and lime-gypsum mortar, later passing to the Counts of Urgell amid disputes through the 12th-15th centuries before ownership by the Dukes of Alba.

Recently restored through archaeological excavations, wall consolidation, and new access walkways, these declared Cultural Interest ruins—spanning Iberian to medieval phases—are now visitable, highlighting the site's pivotal role in frontier conflicts and recent economic revitalization.
