The war tunnel was constructed during the 1425-day long siege of Sarajevo (1992 to 1995 siege), to connect two free territories. The entrance and exit of the tunnel are two houses situated at the opposite sides of the airport. Thus, the tunnel connected Dobrinja and Butmir settlements, and was named "Objekat D-B”. Tunnel construction was initiated in 1993 and completed the same year. The tunnel is 720 meters long, 1.50 meters high. In 1994, narrow rails and mine carts were added to facilitate transportation of food and medicine.
Humanitarian aid was delivered through this tunnel, and wounded soldiers sent out of Sarajevo over Igman mountain. Politicians and world-known reporters such as Susan Sontag used this tunnel to come to Sarajevo and offer their support to the war-torn city. Today, this unique museum structure is one of the most popular tourist attractions in the city.
