Avinguda de la Llum

Avinguda de la Llum (Catalan for Avenue of Light; Spanish: Avenida de la Luz) is a now-closed underground mall in Barcelona, the first one of its kind to open in Europe, open between 1940 and 1990, on a 2000 square-metre site built in 1929 and boasting 68 commercial establishments, including a movie theater. It was underneath Carrer de Pelai, between Plaça de Catalunya, Carrer de Balmes, Carrer de Bergara and Plaça de la Universitat, upstairs of the Ferrocarrils de la Generalitat de Catalunya (FGC) station Catalunya, between its vaults and the street.

Despite initially being part of an ambitious plan to build an underground city from Plaça Urquinaona to Plaça de la Universitat, the urban decay prevalent in the area from the 1960s onwards prompted its progressive abandonment. The Avinguda de la Llum was in a state of decay and had a large homeless population by the time of its closure on May 21, 1990. On the ground upstairs stood an empty triangular area between buildings which came to be called Triangle de la vergonya ("Triangle of shame"), which contributed to the adoption of measures to renovate the area in time for the 1992 Summer Olympics.

Nowadays its main corridor is part of the underground stage of a Sephora store in the El Triangle shopping centre (its successor), while some parts of it are still abandoned and remain closed to the public.
