Commissioned by Ottoman Sultan Mahmud II (reigned 1808–1839) in 1829 and completed in 1832, the tunnel is situated under a hill on the Asian side of the Bosphorus, which is today the terrace garden of the later-built Beylebeyi Palace.[1]

The tunnel with 2.90 m (9.5 ft) clearance served until the 1970s. It was used as museum and exhibition site after its closure.[1]

On 19 September 2016 the tunnel re-opened to traffic in order to ease the traffic congestion on the coastal road in the area under the Bosphorus Bridge,[2] and later shut down again to preserve the historic structure from damage caused by exhaust emissions.
