The B-Werk near Besseringen is the only completely preserved armoured bunker of the Westwall's "B" configuration. The B works were the largest and best-equipped bunkers on the Siegfried Line; there were 32 of them in total. The name is simply the thickness as an abbreviation, B is 1.5 m wall and ceiling thickness. For this reason, this name was usually avoided in order not to give the enemy any indication of the thickness of the fortifications. Instead, a proper name was chosen, usually an animal name or location name.

The B-Werk Besseringen has been preserved undamaged with all its armoury cupolas, which is very unusual because almost all B-Werke were cannibalised and blown up after the war. The armoury cupolas in particular were destroyed. In the meantime, most of them have even been levelled and covered. The B-Werk in Irrel, which is now also a museum, has also been preserved, although it was partially blown up.

It was built in 1938 and 1939 and cost 1.3 million Reichsmarks. 2,800 m³ of concrete, 1,120 t of cement, 5,400 t of sand and gravel,and around 200 t of steel were used. The result is 12 metres high and has 44 rooms on three levels on a floor area of 24.60 metres by 17.80 m. The size was designed for a crew of 85 to 90 people. The building had its own water and electricity supply as well as air filtration systems and was therefore self-sufficient for 30 days. It had two six-shaft turrets, an observation cupola and embrasure plates for a flanking system. The armament consisted of a total of five machine guns, an M 19 machine grenade launcher and an FN fortress flamethrower.
