Iberian Site of Puig Castellar Nature · Santa Coloma de Gramenet, Barcelonès, Barcelona The Iberian settlement of Puig Castellar is a fortified site atop the hill of the same name, 303 metres high, above Santa Coloma de Gramenet (Barcelonès), declared a Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection). Founded by the Laietani people around the sixth century BC and abandoned between the third and second centuries BC, it is one of the best-preserved Iberian settlements in the Barcelona area. Its elliptical layout had three longitudinal streets and more than thirty houses, for a population of a little over three hundred inhabitants engaged mainly in farming and livestock raising. Discovered in 1904 by Ferran Sagarra, owner of the land, it was fully excavated between 1922 and 1958, campaigns in which an iron head, a terracotta head of the goddess Tanit and a trepanned skull of Celtic tradition were found. Today it can be visited freely, with explanatory panels and a reconstructed house with a mill. Photo: Margavela (CC BY-SA 3.0) What to see and do in Santa Coloma de Gramenet
