This tunnel in the Bosnian capital of Sarajevo is a museum and a tribute to the city which was under siege for three and a half years.
When the wars erupted following the break-up of Yugoslavia, Bosnian forces surrounded Sarajevo.
On April 6 1992, the siege began.
Edis Kolar is the museum’s curator. The tunnel was built in his family garden and during the siege was the city’s lifeline.
He said: “This tunnel was built by the Bosnian army in 1993 and for two years it was used as the only way for the people of Sarajevo to go in and out. Three thousand went through this small hole every day.”
