Forty years after UNESCO listed its monuments, Mamallapuram has become the main destination for central tourism money in Tamil Nadu. Three schemes have sanctioned work there since 2016. Here is what each one pays for, how much has actually been released, and what the visitor numbers show.
The numbers
Two projects worth ₹129.69 crore are sanctioned for Mamallapuram alone, the Union tourism ministry told the Rajya Sabha on 12 March 2026: a ₹99.67 crore Nandavanam Heritage Park under the Special Assistance to States for Capital Investment (SASCI) and a ₹30.02 crore immersive experience at the Shore Temple under Swadesh Darshan 2.0. A third, older project, the ₹73.13 crore coastal circuit of 2016-17, took in Mamallapuram along with Chennai, Rameswaram, Manapadu and Kanniyakumari.
The pattern of releases tells its own story. The 2016 circuit money has almost all been paid out. The newer projects are largely still on paper, and for the Shore Temple project no release was listed at all as of January 2026.
Three schemes, one town
Each scheme works differently. Swadesh Darshan 1.0 funded themed circuits that strung several towns together. Swadesh Darshan 2.0 funds projects at named destinations. SASCI’s tourism window, titled Development of Iconic Tourist Centres to Global Scale, pays for capital works in states and had 40 projects sanctioned across 23 states, the minister said in a {a(U_LS3834, “Lok Sabha answer of 16 March 2026”)}.
| Scheme | Project | Sanctioned | Amount (₹ cr) | Released (₹ cr) |
|---|---|---|---|---|
| Swadesh Darshan 1.0 | Coastal circuit: Chennai, Mamallapuram, Rameswaram, Manapadu, Kanniyakumari | 2016-17 | 73.13 | 71.03 |
| Swadesh Darshan 2.0 | Immersive experience at Shore Temple, Mamallapuram | 2023-24, revised May 2025 | 30.02 | not shown |
| SASCI | Nandavanam Heritage Park, Mamallapuram | 2024-25 | 99.67 | 112.13 for both TN SASCI projects |
| SASCI | Eco Park at Race Course, Ooty (for comparison) | 2024-25 | 70.23 | included above |

The SASCI release of ₹112.13 crore is reported as one figure for the two Tamil Nadu projects together, Nandavanam and the Ooty eco park, which have a combined sanction of ₹169.90 crore. That is 66 per cent of the sanction, but the answer does not say how it splits between them, so the Mamallapuram share cannot be stated.
Central money sanctioned for the two Mamallapuram-only projects, the Shore Temple experience and Nandavanam Heritage Park, per the March 2026 Rajya Sabha answer; the 2016 coastal circuit is shared with four other towns.
What the Shore Temple project is
The Swadesh Darshan 2.0 annexure released with a government briefing in March 2026, which lists projects sanctioned up to 15 January 2026, shows the Shore Temple project at ₹30.02 crore with no amount authorised or released. The answer records a revision in May 2025 without saying what changed. Neither document describes what the immersive experience will consist of, so claims about light shows, digital galleries or new visitor centres should be treated as unconfirmed until the state or the tourism ministry publishes the plan.
Mamallapuram against the rest of the state
The same answer lists the other central tourism money in Tamil Nadu. Under PRASHAD, the pilgrimage scheme, Kanchipuram (₹13.99 crore) and Velankanni (₹4.86 crore) were sanctioned in 2016-17 and fully paid, while a ₹40.94 crore project for the eight Navagraha temples, sanctioned in 2024-25, had received nothing. Across PRASHAD, ₹59.79 crore was sanctioned and ₹18.85 crore released. A ₹20.01 crore project for Rameswaram island under the Challenge Based Destination Development sub-scheme had received ₹2 crore. A cruise passenger facility at Chennai Port was sanctioned and released at ₹17.24 crore in 2012.
Against these, the ₹99.67 crore Nandavanam park is the largest single-destination sanction in the state, and the two Mamallapuram-only projects together account for more than twice the entire PRASHAD sanction. In this answer the older projects follow one rhythm, smaller sums released in full over several years, while the recent sanctions remain largely unspent.
Who looks after the monuments
Tourism money and conservation are separate streams. The Group of Monuments at Mahabalipuram was inscribed on the UNESCO World Heritage List in 1984 under criteria (i), (ii), (iii) and (vi). The Archaeological Survey of India protects and manages it under the Ancient Monuments and Archaeological Sites and Remains Act of 1958, with its 1959 Rules and the 2010 amendment. UNESCO’s summary names a 100-metre prohibited zone and a 200-metre regulated zone around the property.
UNESCO describes the monuments as in a good state of conservation and names encroachment and unauthorised construction in the prohibited and regulated zones as the main potential threats. That bears directly on the new projects: any heritage park or visitor facility near the monuments has to clear the same 100-metre and 200-metre rules as a private building.
What the visitor numbers show
The ASI counts tickets. In 2019-20, the last year before the pandemic, Mamallapuram’s group of monuments drew 12,60,358 domestic visitors and ranked seventh among centrally protected ticketed sites, just ahead of the Ellora Caves with 12,59,261, according to the India Tourism Statistics 2020 dataset on data.gov.in. It did not appear in the top ten for foreign visitors that year.
District figures give a wider picture. The Statistical Handbook of Tamil Nadu 2022-23 records 73,76,285 domestic and 42,231 foreign tourist arrivals in Chengalpattu district in 2022. That covers every attraction in the district, not just the monuments, but it puts Chengalpattu fourth in the state for foreign arrivals that year, after Chennai, Vellore and Tiruchirappalli.
It’s often said a World Heritage listing brings central money to a site automatically.
The record shows UNESCO listing in 1984 brought no tourism budget. Central funds came through schemes decades later, project by project, and are released in tranches: of the two Mamallapuram-only sanctions, the Shore Temple project showed no release as of January 2026.
What this means for you
- Ticketed entry to the Shore Temple and Five Rathas is run by the ASI, separately from any new state or central visitor facility.
- Building or extending a house near the monuments needs ASI clearance inside the 100-metre and 200-metre zones, whatever the tourism projects bring.
- The Nandavanam park and Shore Temple projects are sanctioned, not built; check the state tourism department for progress before planning a visit around them.
- Visitor numbers are tracked through the ASI’s ticket counts and the state’s district arrivals, which measure different things.
