Museums The
Museum im Ritterhaus displays documents from Osterode's history from the
Middle Ages to the recent past, as well as occasional temporary exhibitions. The
Lichtenstein Cave is an archaeological site near Dorste, in the western part of the municipality. Two inhabitants of the village Nienstedt am Harz, 2 km north of the cave, have the same rare DNA pattern as that found in the skeletal material of a man whose bones were found in the Lichtenstein Cave dating to about 1000 BC.
Architecture In the environs of Osterode there are several
castle ruins, and Lichtenstein Castle between Dorste and Förste. The town
granary built between 1719 and 1722 is one of the most imposing buildings, built to supply the mining villages in the
Upper Harz with grain. Today after a comprehensive renovation it has become the town hall. It is decorated with a bas-relief featuring the 18th-century coat of arms of Great Britain.
Recreation Osterode is the starting point of the 100 km long
Harzer Hexenstieg, a
hiking trail to
Thale. ==Transport==
