This is bunker MM 17 of the PFL 1, the 1st line of defense of the 'Position Fortifiée de Liège'.
MM refers to the sector 'Manaihant-Les Margarins-' where it is the 17th of a total of 20 bunkers.
This bunker is located in the middle of a meadow. The entrance to the bunker is bricked up so no photos of the inside could be taken. Due to the excessive vegetation, the gun opening could not be photographed.
As general information it can be mentioned that this bunker like most bunkers of the PFL are made of reinforced concrete and were built in the early 1930s. The walls and ceiling are 1.30 m thick. They had to withstand shelling with 150mm shells. Only the walls at the rear are slightly less thick, because in principle they were not exposed to enemy fire.
When the bunkers lost their strategic value for the defense of Belgium after the war, the metal of the hatches and doors was sold as scrap metal. Also, most of the plots on which they were situated were sold, so many bunkers are now on private plots. Like bunker MM 17.
