Poblenou was the factory floor of Catalonia, and it still looks it. Brick mills, warehouses, workers' housing and free-standing chimneys stand all over the flat ground behind the beach, several hundred buildings left when the industry went in the 1960s and 1970s. When the city rezoned the area for technology and media firms around 2000, it did not clear them. Sheds were converted, facades kept, and glass offices went up in the gaps, so a single block can hold a nineteenth-century mill wall and a company headquarters.
From the middle of the nineteenth century this ground filled with textile mills, chemical works and gasworks, and with streets of small houses for the people who worked in them. The quarter was called the Catalan Manchester while that meant something. Not all of the conversion worked: Can Ricart, the best-preserved complex of all, is protected, largely shut and partly derelict behind its gates. The quarter's own centre is not the tech district at all but the Rambla del Poblenou, a low shaded street of benches and old shopfronts running down to the sea.
