The Liceu bomb


    On November 7, 1893, the opening night of the season, during the second act of the opera Guillaume Tell, by Rossini, two Orsini bombs were thrown into the stalls of the opera house. Only one of the bombs exploded, but some twenty people were killed, and many more injured. The attack was the work of Santiago Salvador, an anarchist, and it deeply shocked Barcelona, becoming the symbol of the turbulent social unrest of the time. The Liceu reopened its doors on January 18, 1894, but the seats occupied by those killed by the bombs were not used for a number of years. Wikipedia
