According to Wikipedia, Marine Drive is a three-kilometer boulevard in the southern part of the city. It is a 'C'-shaped six-lane concrete road along the coast, which is a natural bay. The official name for the road is: Netaji Subhash Chandra Bose Road. Most of the buildings along the road were built by wealthy Parsis and have an Art Deco look that was popular in the 1920s and 1930s.
