Mainau is maintained as a garden island and a model of excellent environmental practices. It is one of the main tourist attractions of Lake Constance. Beside flowers there is a park landscape with views on the lake. There is also a greenhouse with tropical climate and thousands of butterflies.
Until the Napoleonic mediatisations and secularisations of small German fiefs this island belonged to the Order of Teutonic Knights. It was later sold into private ownership. In 1853 Grand Duke Frederick I of Baden purchased the island as his personal property and built a summer palace there. At the end of World War I Baden became a republic with the abdication of Grand Duke Frederick II of Baden, son of Frederick I. The former Grand Duke retained his private property including Mainau (a controversial referendum to expropriate some of the remaining "private" property of the former ruling houses narrowly failed in 1926 for not meeting the 50% of eligible voters quorum). When he died childless in 1928 the island passed to his sister Victoria of Baden, wife of King Gustaf V of Sweden. Upon her death two years later she bequeathed the island to her second son Prince Vilhelm, Duke of Södermanland and his descendants. In 1932 Prince Wilhem gave Mainau to his only child Count Lennart Bernadotte of Wisborg who owned it until 1974 when he transferred the island to a foundation. Count Bernadotte formed Enterprise Mainau GmbH in 1991 as a private enterprise to manage the island for the benefit of the Lennart Bernadotte-Stiftung. The Count remained active in managing Mainau until his death in 2004 but appointed his second wife Sonja co-manager in 2001. Lennart's widow Sonja Countess Bernadotte af Wisborg and his children ran both the foundation and the management company until 2007. Since January 2007 Bettina Bernadotte, the eldest daughter of Lennart and Sonja Bernadotte, directs the Mainau GmbH as the current manager.
Flora and fauna
Mainau is a "flowering island" notable for its parks and gardens. Frederick I, Grand Duke of Baden, created the island's arboretum, which now contains 500 species of deciduous and coniferous trees, many exotic and valuable, including fine specimens of Sequoiadendron giganteum (1864) and Metasequoia glyptostroboides (1952). The island also contains about 200 rhododendron and azalea varieties.
The Italian Rose Garden laid out geometrically with pergolas, sculptures, and fountains, and includes some 500 rose varieties. The Mediterranean terraces contain exotic pot plants, including palm trees, agaves, cacti, and Bougainvillea. The island as a whole contains about 30,000 rose bushes representing 1,200 varieties, and about 20,000 dahlias of 250 varieties.
Due to being inside a rather large lake, the climate of this island is rather distinct from other European places at the same latitude.
