in the shape of a three-quarter circle with 18 towers including the actual castle area centred on the North Tower of the castle, 860 m in diameter, was planned. The real purpose of the project was never clearly defined. Inside of this castle area buildings were planned for the exclusive purposes of the Reichsführung-SS (Reich Leadership-SS). The main road of an SS village was also to be centred on the North Tower of the castle with a diameter of 1270 m. This road was to be connected with three radial roads and gates with the castle area. The residential area was to be placed in the northwest, the centre of the village in the north, and the SS-barracks in the west of the castle area; between the barracks and village a villa colony for higher SS-leaders; in the southwest farmsteads. In the architectural plans from 1941, the estate had the shape of a spear pointing towards the north; the 2 km long access avenue with four tree rows road looks like a spear shaft with an access to the Rhynern – Kassel Reichsautobahn (freeway) to the south. The plan from 1944 shows the castle as the top of a triangular estate surrounded by further buildings. The plans also included a "Hall of the High Court of the SS" (Saal des Hohen Gerichtes der SS), streets, parkways, magnificent buildings, a dam with a power plant, freeway accesses and an airport. From 1941 on (after Hitler's successful military campaigns against Poland and France) the architects called the complex the "Center of the World". It was to be finished within twenty years. The complex was to be a center of the "species-appropriate religion" (artgemäße Religion) and a representative estate for the SS-Führerkorps (SS leader corps). If the plans had been realized, the entire village of Wewelsburg and adjacent villages would have disappeared. The population was to be resettled. The valley was to be flooded. 250 million Reichsmark were budgeted for the estate. North Tower Inside the North Tower two mythologic designed rooms were created (1938–1943): The Obergruppenführersaal (SS Generals' Hall) and the Gruft (vault). Their ceilings were cast in concrete and faced with natural stone. On the upper floors a further hall was planned. The axis of this tower was to be the actual "Center of the World" (Mittelpunkt der Welt). A preparation for an eternal flame in the vault, a swastika ornament
