Nagara Style — Key Changes

42nd Amendment Act	1976	This amendment inserted Article 48A (Protection and improvement of environment and safeguarding of forests and wild life) and Article 51A(g) (Fundamental Duty to protect and improve the natural environment including forests, lakes, rivers and wild life, and to have compassion for living creatures). While not directly about monuments, it laid the constitutional groundwork for environmental protection, which implicitly includes the protection of cultural landscapes and heritage sites from environmental degradation.	Strengthened the constitutional mandate for environmental protection, which can be broadly interpreted to include the preservation of the physical environment surrounding heritage sites, ensuring their long-term survival against pollution and unchecked development. It provides a foundational principle for broader heritage conservation efforts.
Ancient Monuments and Archaeological Sites and Remains (Amendment) Act	2010	This amendment to the AMASR Act, 1958, introduced stricter provisions for the protection of ancient monuments. It declared a 'prohibited area' of 100 meters around protected monuments where no new construction is allowed, and a 'regulated area' of 200 meters beyond the prohibited area where construction requires permission. It also increased penalties for violations.	Significantly enhanced the legal protection for Nagara temples and other ancient monuments by creating buffer zones to prevent encroachment and preserve their historical context. This directly impacts urban planning and development around heritage sites, ensuring their physical integrity and visual sanctity. It is crucial for preventing damage to these invaluable architectural assets.
