Description: The reinforced position of the city of Liege (Belgium) was a part of an extensive network of fortresses as a protection against an invasion by an enemy. It forms an arc that reaches from Comblain-au-Pont to Visé.
The defence lines around Liege stretched over a length of 60 kilometres and comprised strong ‘modern’ blockhouses (Tancremont, Battice and Aubin-Neufchâteau) and smaller bunkers. The line formed a shield around the city of Liege and was constructed in the period 1934 – 1935.
The reinforced position of Liege was divided in defensive lines:
- The front positions with 65 shelters;
- Defence area Liege 1 included 178 bunkers and the three aforementioned strong blockhouses;
- Defence area Liege 2 consisting of 62 bunkers and 6 modernized old fortresses;
- Defence area Liege 3 with 41 bunkers;
- Defence area Liege 4 with 37 bunkers and 2 modernized old forts.
The observation bunker MN18 can be found in defence area Liege 1, Margarine – Neufchâteau (MN). This area comprised 31 bunkers, of which only 3 were in use: the bunkers MN18, MN11 (Macra) and MN29 (Bois del Fiesse / Croix de Charneux). In these last two bunkers serious dramas have taken place.
