Osterburg

About

The Osterburg (German: [ˈoːstɐbʊʁk] ) is a castle located conspicuously on a hill in the middle of the town of Weida in the county of Greiz in the German state of Thuringia.

Its 54-metre-high bergfried is the third highest and one of the oldest surviving bergfrieds in Germany. Above its second array of battlements there is a watchman's parlour, which accommodated a watchman until 1917. On the terrace there is a monument which records that this was the furthest south that the ice sheet came in Germany during the Elster glaciation.
