Marine Drive is a 3-kilometre-long boulevard in South Mumbai in the city of Mumbai. It is a 'C'-shaped six-lane concrete road along the coast, which is a natural bay. The road links Nariman Point to Babulnath and Malabar Hill. Marine Drive is situated over reclaimed land facing west-south-west. The bay is part of the Arabian Sea.
The official name for this road, though rarely used is, Netaji Subhash Chandra Bose Road. It was earlier known as Sonapur to local Marathi people. The highlight of Marine drive is the beautiful promenade along the road where many of the citizens take in a breath of fresh air and view the setting sun. The promenade is lined with palm trees. At the northern end of Marine Drive is Chowpatty Beach. This is a popular beach famed for its Bhel puri (local fast food). Many restaurants also line this stretch of the road. Further down this road lies Walkeshwar, a wealthy neighbourhood of the city, also home to the Governor of Maharashtra.
Most of the buildings which were built by wealthy Parsis sport an art deco look that was popular in the 1920s and 1930s. Miami in the United States is the only city in the world that has more art deco buildings along the seafront than Mumbai.
Marine Drive is also known as the Queen's Necklace because if viewed at night from an elevated point anywhere along the drive, the street lights resemble a string of pearls,forming a necklace. It is also the world's largest viewing gallery and hence has been a host to a number of events that take place along the promenade.
