Mumbai is famously known as the City of Seven Islands, a name that reflects its fascinating geographical history and remarkable transformation over the centuries.

Mumbai, Maharashtra, is one of India’s most famous metropolitan cities, celebrated for its financial markets, Bollywood film industry, historic landmarks and vibrant coastal culture. But centuries ago, the city looked very different. Before becoming the bustling metropolis we know today, Mumbai consisted of seven separate islands surrounded by the Arabian Sea and tidal creeks. Through land reclamation, causeways and major engineering projects, these islands were gradually connected, creating the foundation of modern Mumbai.

The seven original islands are commonly identified as Bombay Island, Colaba, Little Colaba (Old Woman’s Island), Mahim, Worli, Parel and Mazagaon. Their history is closely linked to fishing communities, maritime trade and the development of Mumbai as an important port under Portuguese and British rule. Today, the legacy of these islands remains an important part of the city’s identity and fascinating history.

From the famous Gateway of India to the historic neighbourhoods of Mahim and Mazagaon, Mumbai offers a unique combination of heritage, modern development and coastal beauty. Exploring the story of the seven islands reveals how geography, trade and human ingenuity transformed a group of islands into one of India’s most influential cities.

Bombay Island was the principal island around which much of modern Mumbai developed. Its natural harbour and strategic coastal position made it an important location for maritime trade, shipping and administration. During British rule, the area around Bombay Fort became the centre of commercial activity and urban development. As the city expanded, reclamation projects gradually connected the island with neighbouring landmasses, helping create the larger city we see today.

Little Colaba, commonly known as Old Woman’s Island, was a small island situated near Colaba and Bombay Island. Although it is less widely recognised today as a separate geographical feature, it played a part in the historic landscape of the Bombay archipelago. Over time, coastal connections and land reclamation removed the separation between these areas. Its history illustrates how even small islands contributed to the formation of Mumbai’s present-day geography.

Parel was one of the northern islands of the original Bombay group. Its history reflects Mumbai’s transformation from a landscape of villages and open land into an industrial and commercial centre. During the nineteenth and twentieth centuries, the wider Parel and central Mumbai area became strongly associated with textile mills, workers’ neighbourhoods and industrial employment. As manufacturing declined in many former mill districts, redevelopment introduced offices, residences, shopping destinations and modern commercial buildings.

Mumbai’s transformation from seven separate islands into a connected metropolis is one of India’s most fascinating stories of geography, engineering and urban development. Bombay Island became the historic centre of the city, Colaba developed into a renowned heritage and tourism district, Mazagaon maintained its connection with the harbour, Worli preserved its coastal character, Parel reflected the industrial age, and Mahim retained a rich cultural history. Little Colaba, meanwhile, reminds us of the smaller geographical features that formed the original island group.

Today, Mumbai is far more than a financial and entertainment capital. It is a city shaped by generations of fishing communities, traders, engineers, workers and migrants. Understanding the history of its seven islands helps explain how the city’s landscape evolved and why its coastline remains so important. The legacy of the seven islands continues to make Mumbai a remarkable example of how history and human ambition can shape a modern city.
