During the late 18th century, Byculla was an extension of Mazagaon, one of the seven islands that originally formed the city of Mumbai. The area was low-lying Flats inundated during the high tide through the Great Breach at Mahalaxmi. However, the breach was closed by the Hornby Vellard project in 1784, which joined all seven islands of Mumbai into a single island.
