Imperial Palace of Goslar

The Imperial Palace of Goslar is a historical building complex at the foot of the Rammelsberg hill in the south of the town of Goslar north of the Harz mountains, central Germany. It covers an area of about 340 by 180 metres. The palace grounds originally included the Kaiserhaus, the old collegiate church of St. Simon and St. Jude, the palace chapel of St. Ulrich and the Church of Our Lady. The Kaiserhaus, which has been extensively restored in the late 19th century, was a favourite imperial residence, especially for the Salian emperors. As early as the 11th century, the buildings of the imperial palace had already so impressed the chronicler Lambert of Hersfeld that he described it as the "most famous residence in the empire". Since 1992, the palace site, together with the Goslar's Old Town and the Rammelsberg has been a UNESCO World Heritage Site.
