evidence: Lake Constance’s beautiful natural landscape is dotted with historic castles, towers and churches that each tell their own story of the region’s long history. Make sure to see these sights when visiting the famous European lake and all of its districts. One of the most important sights on the Swiss side of Lake Constance, Rhine Falls is the largest waterfall in Switzerland at 150 metres in width and 23 metres in height. After walking through the lovely Laufen Castle, an elevator takes visitors to a platform overlooking the magnificent waterfall. [...] Lake Constance’s famous flower island is indeed a giant garden in full bloom overlooking the beautiful lake. The arboretum on the water was created by the late Frederick I, the Grand Duke of Baden, who purchased the island in 1853 and used the beautiful island palace as his summer retreat.
