Insel Mainau is an island on the south shore of the Überlinger See (Lake Constance) near the city of Konstanz in Baden-Württemberg. Owned by the Lennart Bernadotte-Stiftung, which was established by Prince Lennart Bernadotte, the Count of Wisborg, the island is maintained as a garden island, and it is a model of excellent environmental practices.

The island is home to exquisitely manicured flowering gardens, a greenhouse with tropical climate and thousands of butterflies, and beautiful park landscapes with glorious lake views. Mainau Bay is also the location of the university sailing club. Insel Mainau is one of Lake Constance’s most popular tourist attractions.
