Swan Island is an artificial island located in the southwestern part of the city of Kassel, and also includes a distinctive temple, which is a small building in terms of dimensions but certainly has its own charm, and the Swan Island has an attractive romantic character. In fact, the island was built on a circular floor plan, which gave it a distinctive character in terms of shape, and the water surrounds the circular island from all sides, to form a painting of nature. It's easy to enter the island in winter when the pond freezes, and in summer it's hard to reach, but you can walk or swim through the water to get there.
