History of Marine Lines
The history of Marine Lines is one of the most fascinating stories of British colonial military heritage, ambitious land reclamation, architectural excellence, and cultural vibrancy in all of Mumbai. The very name of this locality is steeped in British India’s military history, and the landscape that grew around it became one of the most iconic urban vistas in the entire country.
The Name — Marine Battalion Lines
The name “Marine Lines” originates from the Marine Battalion Lines, a British colonial military barracks established in the mid-19th century to accommodate the 10th Marine Battalion of the Bombay Pioneers. The word “Lines” in the military context referred to rows of barracks where soldiers were housed — a common British military terminology used across colonial India.
Marine Lines got its name from the Marine Battalion Lines, a military establishment built by the British during 1800s. This historical military installation marked the area’s transition from earlier settlements, including the older locale known as Sonapur, which featured traditional crematoriums.
Ancient Origins — Sonapur
Before the British established their military barracks, the area now known as Marine Lines was historically called Sonapur — a name still referenced in some older maps and records of Mumbai. The area was part of the broader Back Bay shoreline of the island of Bombay, with the natural coastline curving gently westward.
Marine Lines [Eastern side] does not have a large residential population but has an enormous floating population consisting of office-goers, traders and shopkeepers. It is the most densely populated area in the world with 291,981 people per square mile.
The Back Bay Reclamation Scheme — 1920s to 1940s
One of the most significant events in Marine Lines’ physical transformation was the British colonial government’s Back Bay Reclamation Scheme. What began around 1915 and ended in 1940 was a construction resulting in a 3.6 km long C-shaped scenic boulevard that connected the Nariman Point in the South to Girgaon Chowpatty in the north.
This ambitious land reclamation project expanded Mumbai westward by reclaiming land from the Arabian Sea, creating the famous Marine Drive promenade that runs alongside Marine Lines. Marine Drive, often referred to as the Queen’s Necklace, is a 3-kilometre-long promenade along the Netaji Subhash Chandra Bose Road in Mumbai. The road and promenade were constructed by Pallonji Mistry in 1940. It is a banana-shaped, six-lane concrete road along the coast of a natural bay. (The Urban Anecdotes)
The Art Deco Heritage — UNESCO World Heritage
The land reclaimed along Marine Drive was developed into one of the world’s most remarkable architectural ensembles. The iconic Art Deco line up was built on land reclaimed under Backbay Reclamation Scheme along the city’s western sea face. Indian architects designed 35 buildings that create a uniform massing along the promenade that is one of a kind.
In 2018, the Art Deco buildings lining Marine Drive, along with Victorian Gothic buildings elsewhere in South Mumbai, were collectively recognized as a UNESCO World Heritage Site meaning they cannot be destroyed. Marine Drive has the second-largest concentration of Art Deco buildings in the world, after Miami in the United States of America.
The Queen’s Necklace
Marine Drive is known as the Queen’s Necklace because, when viewed at night from an elevated point anywhere along the drive, the street lights resemble a string of pearls in a necklace. (Google Arts & Culture) This iconic description has made Marine Drive and Marine Lines one of the most photographed and celebrated urban vistas in all of India.
The Marine Lines Railway Station — 1867
Marine Lines railway station is a prominent halt on the Western Line of the Mumbai Suburban Railway, serving the bustling South Mumbai locality since its opening in 1867 as part of the Bombay, Baroda and Central India Railway’s expansion. This makes it one of Mumbai’s oldest railway stations, predating the formal development of Marine Drive by several decades.
The Liberty Cinema — 1949
Another highlight is the Liberty Cinema, an iconic Art Deco theater in the heart of Marine Lines that opened in 1949 as a showcase for Hindi films, earning the nickname “Showplace of the Nation.” With a capacity of 1,200 seats, it continues to screen Bollywood movies and has undergone restoration efforts to preserve its architectural heritage.
The Taraporewala Aquarium — 1951
Built in 1951, it is India’s oldest aquarium and is named after the Parsi entrepreneur D.B. Taraporewala, who provided funds for its development. The aquarium has been a beloved landmark of Marine Drive for over seven decades.
