In XIV c. on the top of Birutė hill astronomical observations were carried out. The replica of this paleoastronomic observatory was constructed north of Sventoji settlement, not far from Health center “Energetikas”, and called “Žemaičių alkas” (Samogitian sanctuary). In 1998 wooden columns made by folk artists were put up here. Each column corresponds to the names of mythological gods and goddesses of the Balts. When the sun goes down to the sea by the help of these columns it is possible to fix calendar holidays, which come from paganism.
