Why is Kolkata known as the “Science City” of India: The story behind its scientific legacy

Kolkata has long carried the reputation of being a city of libraries, laboratories, observatories and public debate. Its connection with science did not emerge from a single institution or government slogan. It grew gradually through universities, colonial-era research centres, scientific movements and generations of Bengali intellectual culture that treated scientific discussion as part of ordinary public life. Yet over the years, one particular landmark began shaping this identity more visibly than any other. On the eastern side of the city, beside busy roads and expanding neighbourhoods, Science City became both a tourist attraction and a symbol. The phrase “Science City of India” started attaching itself to Kolkata partly because of this institution, though the story behind that label is wider, older and more uneven than it first appears. Cities are often remembered through symbols rather than official definitions. Mumbai became associated with finance, Chennai with automobiles, Bengaluru with technology. Kolkata’s connection with science stayed alive because the idea already existed culturally before Science City amplified it physically. The city's long-standing academic environment, public lectures, book culture and historic part of Kolkata's identity even as other Indian cities expanded rapidly through newer industries and technological growth. Long before Science City was built, Kolkata already occupied a distinct place in India’s scientific history. Institutions connected to astronomy, medicine, engineering and statistics developed here during the colonial period and continued expanding after independence. Public lectures, science clubs and Bengali science magazines also became common in the city in a way that was less visible elsewhere.This atmosphere mattered. Scientific discussion in Kolkata often moved outside classrooms and laboratories into coffee houses, newspapers and middle-class homes. The city produced figures associated with physics, economics, mathematics and medical research, while organisations promoting scientific awareness became active across West Bengal. Over time, science became tied to Kolkata’s cultural identity almost as strongly as literature or theatre. The construction of Science City in the late 1990s gave this identity a physical centre that ordinary visitors could immediately recognise.According to a study published on ResearchGate, titled “Science City – Landmark of Kolkata Turns 25”, the complex was developed by the National Council of Science Museums and opened in phases from 1997 onward. The paper describes it as one of the largest science centres in the Indian subcontinent and notes that it was designed not merely as a museum, but as a large-scale public science environment intended for people of different age groups. That distinction mattered because Science City was never organised like a quiet exhibition hall. It mixed entertainment with scientific demonstration. Visitors could enter interactive galleries, motion simulators, space-related displays and outdoor exhibits instead of moving silently past glass cases. School groups became a constant feature of the complex. The study also points out that the institution gradually turned into one of Kolkata’s most recognisable urban landmarks. Tourists who may not have known much about the city’s academic history still associated Kolkata with science because of the scale and visibility of the centre itself.Many Indian cities have museums, though few have developed science communication on this scale. According to the report by the Ministry of Culture, it drew people who would not normally visit academic institutions. Families came during the holidays. Students arrived on school excursions. Travellers treated it as part of sightseeing routes alongside historical monuments and cultural centres.Some of its exhibits helped strengthen this public appeal. The “Science on a Sphere” installation, described on the official Science City website, projects planetary and environmental data onto a suspended globe, allowing visitors to visualise climate systems, ocean currents, atmospheric movement and planetary surfaces in motion. The presentation turns complex scientific information into something visually immediate rather than purely theoretical.That approach shaped the identity of the institution. Instead of presenting science as distant expertise, it attempted to place scientific curiosity inside everyday recreation. In Kolkata, where educational culture already held social importance, the idea found a ready audience.The phrase “Science City of India” sounds definitive, though the reality behind it is less formal. There is no official national designation declaring Kolkata as India’s science capital. The title survives mostly through cultural usage, tourism language and the visibility of the Science City complex itself.A report published in Down To Earth examined this contradiction from another angle. It discussed how Science City emerged with ambitious goals linked to science education and public engagement, while also facing questions about commercialisation, visitor numbers and maintenance pressures over time. The report suggested that balancing entertainment with genuine scientific learning was not always straightforward.That tension still exists in many large public science institutions. Attractions draw crowds, but educational depth can become uneven depending on how visitors interact with the space. Kolkata’s association with science, therefore, rests not only on one building, but also on the city’s broader intellectual traditions that existed before it.
