This is bunker BV 23 in Tancrémont wood at Pepinster.
Bunker BV 23 is part of the sector Becco-Vesdre (BV) of the 1st line of defense for de city of Liège, la Position Fortifiée de Liège (PFL 1) and belongs to fort Tancrémont.
The bunker is well hidden in the Tancrémont wood. You might miss it when you search for it. There is many overgrowth with ivy and bushes. The entrance is below groundlevel. The cast iron door is gone and replaces with a bar fence door.
The entrance of the bunker is 3 m. below ground level.
The walls and ceiling of the bunkers from the PFL were standard 1.30 m. thick and of reinforced concrete. They had to be able to withstand shells of 150 mm. To illustrate, the caliber of shells a Königstiger could fire was caliber 88 mm. Thus, only heavier caliber field guns could penetrate the concrete and potentially destroy the bunker.
The bunkers were built in the 1930s.
After the war, when the bunkers lost their strategic value for the Belgian army, the plots of land on which they stood were sold. All the metal of the hatches and doors was sold as scrap metal. Hence the that most bunkers are now on private plots.
