Miedzyrzecz Reinforced Region

Miedzyrzecz Reinforced Region is a fortification system built between 193 and 1944 located between the Oder and Warta rivers in the Lubusz region. It stretches close to 80km between the cities of Gorzow Wielkopolski and Zielona Gora.

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”.

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.

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.
