Rabindra Sarobar has been a fixture of south Kolkata life for nearly a century — the morning-walk lake, the evening-jog lake, the lake where generations of the city have gone to escape the concrete for an hour. What it hasn’t had, oddly, is a place that tells its own story. That’s about to change. The Kolkata Metropolitan Development Authority (KMDA), which looks after the 192-acre waterbody, is turning a long-abandoned school building on the lake premises into a dedicated heritage archive charting the lake’s full history and biodiversity.
From a shuttered school to a heritage archive
The building at the centre of this project has a story of its own. Known as Vidyasagar Academy, it once served as a primary school for underprivileged children in the neighbourhood around the lake. It fell into disuse in 2009 and, by KMDA’s own account, had since become a magnet for unlawful activity, especially after dark.
That building has now been fully restored, repainted, and had its boundary wall repaired, clearing the way for its new role as an archive documenting Rabindra Sarobar’s history and ecology. Urban Development and Municipal Affairs minister Agnimitra Paul has approved the plan, and KMDA’s planning wing has begun preparing a Detailed Project Report for the archive itself.
Why restoration, not new construction
Rabindra Sarobar operates under strict environmental oversight. The National Green Tribunal bars any fresh construction on the premises, which is why KMDA has been careful to describe this project purely as a restoration. “No new construction is allowed within the Rabindra Sarobar premises as per directions of the National Green Tribunal and we have strictly abided by it. The existing building has only been restored and there has been no modification or extension,” a senior KMDA official said.
What the archive will actually contain
According to KMDA, the archive is meant to fill a genuine gap: despite being a century-old lake, Rabindra Sarobar has never had a proper chronological record of its own history. The plan is to present that history through visuals and infographics designed to draw in visitors rather than a dry academic display.
KMDA is also expected to lean on the West Bengal Biodiversity Board (WBBB), which has already compiled a book on the lake’s biodiversity, for the archive’s ecological content. The numbers the WBBB has documented give a sense of just how much life the lake supports for a waterbody surrounded by dense city on all sides:
- 12 species of mammals across 8 families
- 11 species of reptiles across 6 families
- 5 species of amphibians across 3 families
- 107 species of birds across 46 families — 69 resident, 23 long-distance migrants, 14 local migrants, and 1 summer visitor
A century-old lake with National Lake status
Rabindra Sarobar, originally known as Dhakuria Lake, was declared a National Lake on December 3, 2001, under the National Lake Conservation Plan. That status is part of why construction on the premises is so tightly restricted, and it’s also why an archive documenting the lake’s ecological importance is a natural fit for the site rather than an add-on.
Good timing for birdwatchers
For anyone who visits the lake regularly, the WBBB’s bird count is a useful reminder of what to look out for beyond the usual morning walkers and boating crowd. With 23 long-distance migrants and 14 local migrants recorded at the lake, the cooler months from around October through February tend to be the richest stretch for spotting visiting species, alongside the resident birds present year-round. An archive with proper documentation could make Rabindra Sarobar a more deliberate stop for casual birdwatchers, not just an accidental one.

Frequently Asked Questions
Where exactly will the Rabindra Sarobar archive be located?
Inside the restored Vidyasagar Academy building, a former primary school that sits within the Rabindra Sarobar premises and had been lying vacant since 2009.
Is new construction happening at Rabindra Sarobar for this project?
No. KMDA has stated explicitly that only the existing building has been restored, in line with National Green Tribunal restrictions that bar new construction on the lake premises.
When did Rabindra Sarobar become a National Lake?
It was declared a National Lake on December 3, 2001, under the National Lake Conservation Plan.
Who is providing the content for the archive?
KMDA’s planning wing is preparing the Detailed Project Report, with the West Bengal Biodiversity Board expected to contribute biodiversity data drawn from its existing research on the lake.
The bottom line
It’s a small project in square footage but a meaningful one for a city that doesn’t always do a great job preserving its own civic history. A century-old lake that has quietly supported over a hundred bird species and dozens of mammal, reptile, and amphibian species is finally getting a place to tell that story — built, fittingly, inside a school that once served the neighbourhood around it.
