Since 1992, the palace district, together with Goslar's Old Town and the Rammelsberg Mine have been designated as a world heritage site by UNESCO. Henry Moore's sculpture, Goslar Warrior 1973-1974 has stood in the palace gardens since 1975. It was named for the town after Moore received Goslar's Goslarer Kaiserring art prize in 1975. On warmer summer evenings the large meadow around the two statues in front of the Imperial Palace used to be a popular meeting place for all kinds of people. Today there is a ban on alcohol and assembly anywhere in the palace grounds.
