Mainau is a 45-hectare horticultural park located on an island in Lake Constance, primarily known for its seasonal flower displays and the Baroque-era Mainau Castle. The island is owned by the Bernadotte family and functions as a managed tourist destination with extensive botanical collections, including an arboretum featuring giant sequoias. Visitors can explore a butterfly house, which is among the largest in Germany, alongside varying seasonal displays such as tulip shows in spring and dahlia exhibits in autumn. The castle, constructed in the 18th century, serves as the central architectural anchor of the grounds. The island is connected to the mainland via a pedestrian bridge. The garden layout is designed to rotate its floral theme annually. The location serves as a model for sustainable garden management in the Bodensee region.
