Goslar is a historic town in Niedersachsen (Lower Saxony), Northern Germany, on the slopes of the Harz mountains. The Altstadt (old town) and local mines have been declared UNESCO World Heritage Sites. The town lies 40 km from Braunschweig and 70 km from the state capital Hannover. It has a rich cultural, political, and industrial history. Salian Emperor Henry I founded it in the 10th century after the discovery of silver deposits. The wealth derived from silver mining brought Goslar the status of an Imperial City, which attracted the interest of the Holy Roman Emperor. The medieval Imperial Palace was built in the 11th century and became a summer residence for the emperors, especially Henry III of Germany. Henry’s heart is buried in Goslar, his body lies in the family vault in Speyer Cathedral. Local sites include the 16-century town hall and the old mines, which now house a museum. During the Cold War, Goslar was a major garrison town for the West German army and the border police. After the fall of the Berlin Wall, the barracks were vacated. There’s skiing here in winter.
