 To the south of the monument is the Sanctuary building, comprising a rectangular body of three wings, with facades covered with masonry brick.In 1987 there was a plan to construct 18 different buildings and spaces around the monument (including a restaurant, lookouts, a commercial complex, a parking area and a sanctuary), of which only a few of these structures were built.The most notable was the construction of the visitors' centre and the "Sanctuary" building.
