This protected cityscape area has become an architectural curiosity of international fame because of the rare diversity of styles. The multitude of architectural designs and decorations is simply breathtaking. One can find a house in neo-gothic style standing right next to a mansion in Art Nouveau architecture. The real showpiece is the prestigious Cogels-Osylei street with splendid examples of fin-de-siecle architecture. The district isn't that large, so the best way to visit it is by taking a stroll through the different streets.
