The core of the city is an avenue, some say, a fashion promenade: the Konigsallee, affectionately dubbed the ‘Ko\ Not only Diisseldorfers believe it to be one of the most splendid boulevards of the Old World. It is only one kilometer long, but nobody dashes through the ‘Ko’ in 12-15 minutes, it is not for rushing. It is lined with the finest shops, boulevard cafes and small restaurants. Chestnut and plane trees make a green roof over the 85-meter wide triumphal avenue. Everyone strolling along the elegant ‘Ko’ will enjoy the atmosphere of fashion and art that pervades this city on the Rhine. In the historical center every building houses a bar, which, lined up together, makes this the ‘longest bar in Europe’. The cultural scene in Diisseldorf shows art from several centuries. 20th-century masterpieces are represented particularly in the Collection of the State of North Rhine-Westphalia. Heine’s tracks lead back to Old Diisseldorf, to Bolker Strasse, where a plaque marks his birthplace. Diisseldorf is a world-famous congress city and trade fair venue on the Rhine. There is plenty of space at the Trade Fair Convention Center. Even the most enthusiastic delegate needs a break once in a while. And breaks he/she shall have, of no mean sort – whether his/her interest is art, culture, music, fashion, shopping, entertainment, or the Old Town.
