The Rugard is a high elevation near the village of Bergen. It is a moraine formed during the last ice age, on which a castle was located from the 9th century until the 14th century, where the Ranen princes resided. Some of the castle ramparts have been preserved to this day.
In his 1821 painting "The Rugard on Rügen", Karl Friedrich Schinkel drew a view that shows the Rugard in its unwooded state. Today it is surrounded by woodland, through which a 2.5 km nature trail has been leading since 1984. In the 1870s, the tower erected on the Rugard was erected as a monument to Ernst Moritz Arndt, who was born in Rügen. The 27 m high landmark of Bergen offers a wonderful view over the town and large parts of the island. In the immediate vicinity is the "Rugard" adventure world with island toboggan run, climbing forest, go-kart and quad track and mini golf course.
