The Gate of Centelles Monument · Centelles, Osona, Barcelona El Portal de Centelles is the old monumental gateway into the town of Centelles, in Osona, declared Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection) and part of the walls built in the 16th century. On the outer face it has a round arch with voussoirs, crowned by the coat of arms of the Centelles family, and retains four merlons and two blunderbuss loopholes; on the inner side, with no defensive features, it shows a moulded window, a small coat of arms and a large flat-vaulted arcade. The old sagrera of Santa Coloma, the municipality's original name, already had walls from 1329, but the present walls were raised between 1537 and 1565, under Baron Guillem Ramon II de Centelles, Count of Quirra. The Portal was remodelled and restored in 1919 by the architect Jeroni Martorell i Terrats. Photo: Enric (CC BY-SA 3.0) What to see and do in Centelles
