Bunker MM 3 is the 3rd bunker from the Manaihant-Les Margarins sector of the 1st defense line of the city of Liège, La Position Fortifiée de Liège 1, PFL 1.
The bunker is located in a rugged piece of terrain and over the ages has become increasingly covered with soil and overgrown with bushes and trees. There are still 2 concrete posts present from the barbed wire fence that marked the plot as a military site.
The bunker is still accessible although that will not be easy given the soil present in front of the entrance. The gun opening is sealed with cement. Also remarkable is the absence of ventilation openings at the front.
The bunkers were built in the early 1930s. The walls of the bunkers from the PFL line are 1.3 meters thick reinforced concrete. They could withstand shelling with 150mm shells.
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. From all appearances, the 1st of 2 doors is no longer present, What of the rest of the interior is preserved is unknown.
Also, most of the plots on which they stood have been sold, so many bunkers are now on private plots. In this case it seems to be on a plot of the municipality and is very difficult to reach through some meadows.
