The Tunnel of Hope, or Sarajevo War Tunnel, was dug beneath the airport runway during the 1990s siege to link the encircled city with free territory, allowing food, weapons and people to pass. Today a preserved section and museum tell this remarkable story of survival through photographs, film and personal belongings. A guided visit brings home the reality of the longest siege in modern European history, making it one of the most moving and essential attractions in Sarajevo.
