Lucerna Palace, built between 1907 and 1921 by architect Václav Havel, grandfather of the former Czech president, is one of Prague's Art Nouveau masterpieces. It covers a total area of 21 000m2 and its galleries run between the streets Vodičkova and Stěpánská and Wenceslas Square. Over nine floors (four of them underground), it houses restaurants, shops, cafés, a cinema, concert halls and Prague's most prestigious dancefloor.
