The complex contains gardens, which were originally private gardens before being opened to the public in 1958. The complex is notable for its gardens and outdoor sculptures. Iconic sculptures include the "Knotted Gun", called "Non-Violence", a statue of a Colt Python revolver with its barrel tied in a knot, which was a gift from the Luxembourg government and "Let Us Beat Swords into Plowshares", a gift from the Soviet Union. The latter sculpture is the only appearance of the "swords into plowshares" quotation, from Isaiah 2:4, within the complex. Contrary to popular belief, the quotation is not carved on any UN building.
