Before you enter, you undoubtedly attract the architecture of the building. Both the exterior and the interiors are richly decorated with original details in the avant-garde style inspired parts of famous artist Friedensreich Hundertwasser (Austrian multifaceted artist, famous primarily as an architect, graphic artist and painter. His colorful paintings are permeated by natural shapes and spirals.) And Antoni Gaudi (One of the most important modern architects, Catalonian origin. His work was closely connected with the secession. His greatest works were designed for Barcelona.). Individual elements such as the pervasive mosaic, dancing box, but the golden onion on a chimney emphasize the uniqueness and timelessness of the work.
