The architecture of the Swarovski Crystal Worlds is a unique and captivating blend of art, creativity, and modern design, by multimedia artist André Heller. The museum's interior consists of several themed chambers, each designed by different artists, designers, and architects. A combination of materials have been used, including glass, steel, concrete, and natural stones. The Crystal Worlds' main building is partially buried into the hillside, blending harmoniously with its surroundings for an eco-friendly design. The entrance to the museum is marked by a giant head, made of over 0.8M hand-mounted crystals, becoming an iconic symbol of the Crystal Worlds internationally. The kid-friendly playtower was designed by artist Friedensreich Hundertwasser, which stands as a colourful play area, in contrast to the elegant crystal exhibits of the museum.
