During World War Two the German Armed Forces put an immense effort in constructing fortifications and defense lines. Tens of thousands of bunkers, casemates, trenches, anti-tank walls and obstacles, tunnel systems and factories were built in the five years of war in Europe. Probably the best known of all is the construction of the Atlantikwall.
Although the name falsely suggest it was a single structure, which works really well in propaganda, it was actually comprised of thousands of individual fortifications and constructions that formed the base of a defense system that stretched along the West Coast of Europe. Even today it is very common to find remnants of these constructions in the European landscape.
Documenting bunker construction
During the war the German Army made regular status reports and maps of the construction progress that were filed for administrative purposes. These reports are known as Baufortschrittsmeldung or Baufortschrittskarte. A map would typically show the complete plan of the position or fortification and list the individual bunker types to be constructed together with their construction status.
It is good to note that not every construction was documented in the reports. Sometimes additions or whole constructions were made by the units who manned the position themselves and were left undocumented.
The administration of the reports and maps was the task of the Fortress Engineers or in German; Festung Pioniere. These were divided into different “Festung Pionier Stäbe” (Eng: Staff). Since the German Army had a strict divide between it’s Wehrmacht, Navy and Air Force organizations, these all had their own fortress engineer units. So for the German Navy these would be called Marine Festung Pionier Stab.
These Baufortschrittskarten and Baufortschrittsmeldungen are a rich source of information for anyone interested in WW2. This is why we have shared our collection for your convenience. If you happen to have BFK’s not listed here, please share them with us so we can expand our collection further. Feel free to send us a message through our contact form.
Most of the “Baufortschrittskarte” maps of The Netherlands come from the reports of Marine Festungs-Pionierstab 4 and Marine Festungs-Pionier Gruppe Wassenaar. After the war these reports were archived by the Dutch BRV administration, loosely translated as Bureau for Registration of Defense Works.
Marine Festungs-Pionierstab 4
Most of the Mar. Fest. Pi. Stab 4 reports are dated March 25th 1945, near the end of World War Two in Europe. At that time the Allied advance already reached the South of The Netherlands. The reports listed here are ordered from the North to the South and you can see that on some the reports covering the South certain areas are marked “Vom Feind Besetzt!”, which translates to “Occupied by the enemy”.

The bold black line marks the Anti-Tank moat (Panzergraben). The numbered dots indicate the access points where the Anti-Tank wall could be passed. At the crossings the defense line consisted of a heavy concrete wall (Panzermauer) or dragon teeth (Höckerhindernis). The dashed lines are railroad tracks.
