What could be an architect's favorite place? A spectacular natural space? A construction visited by millions of people every year? Pol Casellas, architect and cultural communicator, is very clear about it: the Bogatell breakwater in Barcelona: “It's close to me and I go there often. It's not idyllic, but for me it's special, I've always been very connected to the sea, and I feel that breakwaters give me a lot of calm”.
