Miedzyrzecz

Miedzyrzecz – updated 15 January 2023.

The Miedzyrzecz Reinforced Region (MRR) was a fortified area built by the Germans in occupied Poland during World War II. It was located in the present-day western part of Poland, east of the city of Poznan and was part of the larger system of fortifications known as the “Reinforced Region East” (RRE). The MRR was designed to protect against a possible Soviet invasion of Germany and to control the population in the area.

MRR

The MRR was made up of a network of bunkers, trenches, and other fortifications, as well as anti-tank ditches and minefields. The fortifications were built using forced labor, mostly by prisoners of war and concentration camp inmates. The MRR was never completed and it was never put to the test during the war. After the war, the fortifications were dismantled and the area was returned to civilian use. Today, some of the fortifications still exist, and some have been turned into museums or other tourist attractions.

Dragon teeth

Built by Nazi Germany with the purpose of protecting the most vital section of the eastern border of Germany, Miedzyrzecz Reinforced Region was a line of 106 reinforced concrete bunkers with 25cm thick walls, steel domes and concrete antitank barriers called “dragon teeth”.

Underground tunnels

21 of the concrete bunkers were connected by a 30 km network of 40m deep underground tunnels containing railway stations, war rooms, workshops, engine rooms, stockrooms and barracks. The whole network of bunkers and underground system of the Miedzyrzecz Reinforced Region were fitted with essential equipment such as lighting, ventilation, plumbing, sewage disposal and communications.

30,000 bats

Miedzyrzecz Reinforced Region remains one of the largest and the most interesting systems of this type in the world today. It is also one of the largest hibernation sites for bats in Europe. Each year over 30,000 of them winter here representing 13 different species.
