The Imperial Palace of Goslar (German: Kaiserpfalz 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 and stands. 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 (Liebfrauenkirche). The Kaiserhaus is the greatest, oldest and best-preserved secular building of the 11th century in Germany. It 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".
