Entenstein Castle is a medieval castle surrounded by a moat situated in the center of the town of Schliengen. The origins of the castle can not be clearly dated. The first use of a building at this location can be traced to Walter of Schliengen in 821. By 1000 a tower house might have been in use. In the 13th century, Rudolf von Üsenberg (1207-1231) was the owner of the castle. The name of the castle derives from the German words 'Ente' and 'Stein', which means duck and stone. By 1525, Entenstein belonged to the nobles of Nagel von der Alten Schönstein and was thus transformed to a more representative manor house.
In 1725 Johann Conrad of Reinach-Hirtzbach, then Prince Bishop of Basel, bought Entenstein castle and used it as the seat of the Upper Bailiwick of Schliengen. In 1805, Entenstein Castle became a district site of the Grand Duchy of Baden. After 1857 Entenstein Castle which was then in the possession of the counts of Andlau, an old German noble house, was reconstructed. In 1970 Entenstein Castle was purchased by the Community of Schliengen and renovated thereafter. Since 1975 it funcitions as city hall of the community of Schliengen.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
