The Sarajevo Tunnel (Bosnian: Sarajevski tunel / Сарајевски тунел), (Serbian: Sarajevski tunel / Сарајевски тунел), also known as Tunel spasa (Тунел спаса, English: Tunnel of salvation) and Tunnel of Hope, was a tunnel constructed between March and June 1993 during the Siege of Sarajevo in the midst of the Bosnian War.
It was built by the Bosnian Army in order to link the city of Sarajevo, which was entirely cut off by Serbian forces, with Bosnian-held territory on the other side of the Sarajevo Airport, an area controlled by the United Nations.
