New Castle of la Gornal Monument · Castellet i la Gornal, Alt Penedès, Barcelona Image of Castellet i la Gornal, not of the place itself. A fortification documented in the 14th century, declared an Asset of National Cultural Interest in 1988, of which only a few worked ashlars survive next to the camí de Clariana; after its decline a farmhouse, the Mas Castellnou, was built with its remains, itself now also in ruins.
