The Swiss Miniatur in Melide, which was opened in 1959, is the only miniature park in Switzerland and is Switzerland on a smaller scale (1:25). There are 130 models of houses, castles and monuments in the open air, distributed throughout the 14,000 square meter park. The detailed and authentic models include well-known sites such as the Heidi Village in Maienfeld, the castles of Burgdorf and Chillon, the Federal Parliament in Bern, and the Cathedral of Milan, the only model that can also be viewed from inside. Eighteen model trains travel between the buildings on approximately 3.5 kilometers of tracks. There are also operating rack-railways, cable cars, suspension railways and ships. Swiss Miniature is also a visual delight, since its models are surrounded by 15,000 flower species and over 1,500 trees.
