The Siege of Sarajevo that lasted for 1,425 days, is the longest siege of a city in the 20th century. This tragic story should be preserved for truth, memory and humanity through construction of the museum. The location of this museum is the "Sarajevo Tunnel of Life", that was the escape tunnel as the only way out of the city and today is a monument. The museum "Sarajevo Tunnel of Life" is based on the concept of contrasts. The contrast between closure and openness, darkness and light, life and death. The architecture of the museum tells the story of the emotions of the siege, the experience of the flight and passes this story on next generations.
