About the bunker
The Přáslavice Bunker or Action 025 is an important military and telecommunications facility from the Cold War era. In its time, it was of great importance for the Warsaw Pact countries. It was one of the buildings with the highest level of secrecy. Even the people who lived in its immediate vicinity did not know about the bunker.
It was one of seven reinforced points on the secret International Cable Line 1, which connected the east (Moscow) and the west (Berlin). Inside it was a civilian and military telephone exchange , as well as secret and encryption technology.
It is one of the largest accessible bunkers in Central Europe. The area of the underground part, which consists of 4 floors, is an incredible 10,000 m² of interior space (to give you an idea, this is the approximate size of two football fields).
It was created in the geographical centre of the former Czechoslovakia. Near Olomouc, in a place where a quarry was once located. This made construction a little easier. It is a skeleton building in which the concrete body was sunk into the ground. The surface was then treated to be perfectly camouflaged.
Soldiers from distant places of the former Czechoslovakia participated in the construction. Due to secrecy , neither they nor their family members knew exactly what construction they were working on. The bunker was kept quiet.
Only those with the strictest security clearance were allowed to enter some parts of the bunker. The complete declassification of the entire building took place only recently, in 2016.
In the Czech Republic, the Přáslavice bunker represents a unique opportunity to see a declassified military facility from the Cold War era. It is authentically equipped with period technology, many of which are functional again thanks to the efforts of enthusiasts.
A number of pictorial and textual materials have been created about the bunker. On the website we bring you the most interesting of them. To get an idea of what it looks like inside, you can watch a video that was taken at the time when we first opened the bunker to the public.
We are pleased that from June 2022 we can talk about the bunker on tours to all those interested in history, telecommunications, military, as well as to all ordinary tourists and visitors.
