A volunteer-led group in Kolkata has illuminated about 92 of the city's heritage buildings in roughly 21 months, drawing new night tours and prompting repairs to long-neglected structures and tower clocks. The initiative, organised under the informal label Kolkata Restorers, seeks to make the city's colonial, religious and civic architecture visible after dark and to catalyse wider restoration work.
The project began when organiser Mudar Patherya raised money to repaint a market dome and then paid to light it after he realised the work could not be seen at night. From that first effort he moved on to light other buildings, using a model in which volunteers provide and install lighting and property owners pay only the electricity cost. The undertaking expanded quickly, with lighting designer Suyash Narsaria adjusting wattages and arranging layered illumination to highlight columns, railings and murals while conserving energy.
The night tours, run by private operators including Sujoy Sen, guide visitors past neoclassical, Gothic and Art Deco landmarks such as the General Post Office, Raj Bhavan (the governor's mansion), the Geological Survey of India building, and religious sites including mosques and synagogues. Participants and locals have compared the effect to seeing Paris by night, saying that the lighting changes familiar façades and makes details visible that are lost in daylight.
As the project grew, organisers encountered structural decay that the illumination made more apparent. Hogg Market, a roughly 150-year-old Gothic market whose clock tower had long stopped chiming, was found to have a worn roof and rotten floorboards. Repairing the clock tower and other elements became a prerequisite to lighting some buildings. That work led to involvement from traditional craftsmen: Swapan Dutta, a fourth-generation clock repairer, has been restoring stoppered tower clocks and expects many of them to chime again after repairs.
Kolkata Restorers does not operate as a formal organisation; Patherya describes it as a loose label and a WhatsApp group that crowdsources funds and labour. He says roughly 22 million rupees (about $250,000) has been spent to restore buildings, clocks and tombstone plaques so far. Patherya contrasts that sum with the cost of a single luxury apartment in the city to argue that modest citizen funding can achieve substantial conservation gains.
The work has required technical experimentation. Narsaria and his team reduced lamp wattages, adjusted positions and used layered lighting to balance visibility with efficiency and to avoid overpowering delicate façades. The project has also faced mundane obstacles such as wildlife chewing wiring and the challenge of finding specialists who can repair century-old mechanisms.
Restorations completed so far include clocks and features in churches, a synagogue and markets, as well as façades such as Queens Mansion and more prominent sites including Raj Bhavan and parts of the Dalhousie government district. Supporters say the visual transformation has rekindled civic pride and drawn fresh attention to the need for preservation in a city whose fortunes and built fabric have changed since it was the capital of British India.
Not everyone sees heritage as an immediate priority amid development pressures. Property owners and officials sometimes prioritise land value and new construction, and funding constraints have limited official conservation. Kolkata Restorers' organisers argue the citizen-led, low-cost model shows how community action can complement public efforts.
Organisers run nighttime tours to showcase the work to residents and visitors; some participants say the illuminated façades make familiar buildings feel newly alive. Patherya has set a goal of lighting 200 buildings, which he says would make Kolkata among the most strikingly lit cities in the country at night because "the architecture is already there." The group continues to fundraise, recruit craftsmen and negotiate permissions with property owners to expand the initiative and to restart more of the city's historic clocks.
The project highlights a combination of grassroots mobilisation, traditional craft skills and contemporary lighting techniques that has made Kolkata's architectural heritage more visible after dark while exposing and beginning to address the decay that long preceded the lights.
