Nuclear Shelter 10-Z

Nuclear Shelter 10-Z is a remarkably well-preserved Cold War bunker buried beneath the city centre. Built in the late 1950s under the Husova Street area, the shelter was designed to protect Communist Party leadership and key personnel during a nuclear attack. The facility is now open for guided tours and retains an extraordinary level of original detail: dormitories with military-issue bunk beds, a period-furnished operations room with Soviet communication equipment, and a medical station with genuine Cold War-era surgical tools.

The tour winds through over 800 metres of corridors. The atmosphere is genuinely unsettling — the decontamination chambers, gas-tight blast doors, and the sober practicality of the whole enterprise communicate the anxious logic of civil defence planning better than any museum display could. Guided tours run regularly and must be booked in advance; the tour takes about 90 minutes and is conducted in Czech and English.

A story
Shelter 10-Z was built in the 1950s as a top-secret nuclear fallout facility intended to protect Communist Party officials and essential services during a nuclear strike. It was classified until after 1989 and most Brno residents had no idea it existed. The shelter is designed to sustain 400 people for up to 14 days, with its own generator, water supply, and decontamination chambers. The bunks, communication equipment, and period furnishings are preserved exactly as they were during the Cold War.
