This radarsite is called Gi 305 (WN Ratibor). It is situated on a hill in the forest north of the IGN designation Le Royannais. It is hard terrain, but besides the St-bunkers other buildings and radar basements remains can be found. The watersupply bunker type 675 was still under construction. The L 406 had an additional watertank.
Also in this strongpoint the 502s have only one chimney.
