[2][3] For a long time research was carried out on the island, because it was believed that it was the legendary center of the cult of Slavic tribe Veleti – Rethra.

[4] In 1969, during archaeological excavations carried out under the direction of the German archaeologist Adolf Hollnagel, two cult figures of oak wood were discovered in the layer dated to the 11th-12th century.

[5] The first, 1.78 meter high, shows two male busts with large eyes, noses and mustaches in headgear (helmets?)

[2] During subsequent excavations, valuable finds were made, such as keys, knives, axes, spear points, temple rings, silver coins and others.

In 1977, another German archaeologist Hartmut Boeck discovered a 40m × 14m rectangular place in the northeastern part of the island, which was growing more and more every year.
