Originally Herzberg Castle was a medieval castle used as a hunting lodge built in the 11th century. The castle was built on the behest of King Lothair III. It belonged to the House of Welf for 700 years. After a fire in 1510 it was rebuilt as a timber-framed castle.
"Unicorn Cave" - even the name of this cave sounds mysterious. For hundreds of years, digging for the bones of the unicorn had been the foremost interest. The bones were ground down to powder in a mortar and sold as "Unicornu fossile" ("excavated unicorn"), a much esteemed medicine over the whole of Europe.
