The 45 hectar Mainau Island lies just off the shores of Lake Constance (Bodensee) the far south-west of Germany, close to Switzerland and Austria. The over 150 year old Arboretum with giant sequoias welcomes you to relax and enjoy nature seasons. Around a million tulips, rhododendrons, scented roses, perennials and colourful dahlias bloom in the park and gardens. Palms and citrus plants lend a Mediterranean flair to the island in summer. The Teutonic castle completed in 1746 and the castle church St. Marien are architectural highlights of the Baroque era and stand in close proximity to 15 metre tall palm trees. Not only nature and garden lovers and relaxation seekers come to the island but also many families.
