Castle of Barrès Monument · l'Esquirol, Osona, Barcelona Image of l'Esquirol, not of the place itself. A 13th-century castle in the district of l'Esquirol (Osona), declared Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection), of which only the base of a tower and a wall survive, covered by vegetation, along with rubble remains of stone and tile. Documented since 1106, it was dependent on the viscounts of Cabrera and defended the sector of the parish of Santa Maria de Corcó. It was destroyed in 1302 during the conflict between James II of Aragon and the count of Empúries, Ponç Hug IV, who was married to the viscountess of Cabrera; its reconstruction was authorised in 1313, though by 1589 no one any longer remembered having seen it standing.
