Regulated and Prohibited Zones Around Monuments

The zoning regulations around centrally protected monuments are primarily governed by the Ancient Monuments and Archaeological Sites and Remains (AMASR) Act, 1958, and were significantly strengthened by the AMASR (Amendment and Validation) Act, 2010. These zones are designed to create a “buffer” that prevents physical damage to the structure, maintains its visual integrity, and ensures the preservation of the archaeological strata surrounding the site.

Classification of Regulatory Zones

The law divides the area surrounding a protected monument into two distinct tiers based on the distance from the “protected limit” (the boundary wall or the outer edge of the monument).

The Prohibited Area (0-100 Meters)

The Prohibited Area acts as a primary shield against urban encroachment and vibrations from heavy machinery.

• No-Construction Mandate: No person, including the owner of the land, can carry out any construction in this zone. This includes residential, commercial, or industrial buildings.
• Exceptions for Maintenance: Necessary repairs and maintenance of existing structures (built before the notification) may be allowed, provided they do not involve new construction or expansion.
• Public Projects: Under the 2010 Amendment, even government agencies are barred from construction here unless the project is deemed essential for the security or safety of the monument or the public, requiring high-level clearance.
• Mining and Quarrying: All blasting, mining, and quarrying activities are banned within this radius to prevent structural cracks caused by seismic vibrations.

The Regulated Area (100-300 Meters)

The Regulated Area is the secondary buffer extending 200 meters beyond the Prohibited Area, totaling a 300-meter protected radius from the monument.

• Permission Requirement: Any individual or agency intending to undertake construction, reconstruction, or massive repair within this zone must apply for a No Objection Certificate (NOC).
• Heritage Bye-Laws: Construction in this zone is governed by “Heritage Bye-Laws” specific to each monument. These laws dictate the height of buildings, architectural facade (to match the monument’s aesthetic), and the use of specific building materials.
• Impact Assessment: The NMA evaluates whether the proposed building will obstruct the “visual cone” or the view of the monument from public vantage points.

National Monuments Authority (NMA) and Competent Authority

To streamline the regulation of these zones, the 2010 Amendment established a specialized administrative hierarchy.

• National Monuments Authority (NMA): A statutory body under the Ministry of Culture. It is the apex body that processes applications for construction in the Regulated Area and recommends them to the Competent Authority.
• Competent Authority (CA): Usually an officer of the rank of Director (Archaeology) or a senior bureaucrat appointed by the Central Government. The CA issues the final permission based on NMA recommendations.
• Heritage Impact Assessment (HIA): For large-scale projects in the regulated zone, the NMA may mandate an HIA to ensure that the development does not adversely affect the site’s “Universal Value.”

Evolution and Proposed Reforms: The AMASR (Amendment) Bill

Recent years have seen debates regarding the rigidity of these zones, especially in dense urban areas like Delhi or Chennai where monuments are surrounded by existing habitations.

• The 2017/2023 Proposals: Recent legislative proposals have sought to allow “public works” (infrastructure projects like bridges, highways, and metros) in the Prohibited Area if no other feasible alternative exists.
• Rationalization of Limits: There is ongoing discussion about moving away from a “one-size-fits-all” 100m/200m rule to a site-specific approach where the buffer is determined by the monument’s size and significance.

• Origin of Limits: The 100m and 200m limits were originally introduced via a 1992 Government Notification but were only given statutory (legal) teeth through the 2010 Amendment.
• Adarsh Smarak: ASI has identified 100 monuments as ‘Adarsh Smarak’ (Model Monuments) where the enforcement of these zones is coupled with enhanced tourist amenities and signage.
• Encroachment Statistics: According to ASI, over 300 centrally protected monuments in India currently face issues of illegal encroachment within their prohibited zones.
• SMARAC Portal: The NMA launched the “Smart Monitoring of Monument Regulated Areas” (SMARAC) portal to enable citizens to apply for construction permits online, using ISRO’s Bhuvan satellite technology to verify the distance from the monument.
• The 100-Year Clause: Remember that these zones apply only to “Ancient Monuments” as defined by the Act, which must be at least 100 years old and declared of national importance.
