Ancient Monuments and Archaeological Sites and Remains Act, 1958 (AMASR Act)

The AMASR Act, 1958 is the main central law that protects India's ancient monuments and archaeological sites that are of national importance. It allows the central government to declare a monument "protected", to look after it, to control digging (excavation) around it, and to stop harmful construction near it. The Archaeological Survey of India (ASI), under the Ministry of Culture, carries out most of this work. Since 2010, the law also creates two safety belts around every protected monument, where building is banned or controlled.

Why does it exist?

India has thousands of temples, forts, stupas, mosques, tombs and ancient sites. Many are hundreds or thousands of years old. Without legal protection, they can be damaged by encroachment (people occupying land illegally), new buildings that block or overshadow them, heavy construction that shakes old walls, or people stealing carvings. Once a monument is damaged, it can never be truly replaced. The Act exists so that the State can stop such harm before it happens.

What does the Constitution say?

Three parts of the Constitution support this law:

• Article 49 (a Directive Principle of State Policy) says it is the obligation of the State to protect every monument, place or object of artistic or historic interest declared by or under a law made by Parliament to be of national importance, from spoliation (damage), disfigurement, destruction, removal, disposal or export.
• Article 51A(f) (a Fundamental Duty) asks every citizen to value and preserve the rich heritage of our composite culture.
• Seventh Schedule: Union List Entry 67 covers monuments and sites declared by Parliament to be of national importance. State List Entry 12 covers other ancient monuments. Concurrent List Entry 40 covers archaeological sites and remains not declared to be of national importance. This is why both the Centre and states protect monuments: the Centre protects the nationally important ones, and states protect the rest through their own laws.

Where did it come from?

• 1861: The ASI was set up, with Alexander Cunningham as the first Archaeological Surveyor. He later became its first Director-General (1871).
• 1904: The Ancient Monuments Preservation Act, 1904 was passed during Lord Curzon's time as Viceroy. It was the first major law to protect monuments in India.
• 1951: After Independence, the Ancient and Historical Monuments and Archaeological Sites and Remains (Declaration of National Importance) Act, 1951 declared many monuments to be of national importance.
• 1958: Parliament passed the AMASR Act, 1958, which replaced the 1951 law and became the main framework. The AMASR Rules, 1959 were made under it.
• 1992: A government notification of 16 June 1992, under the 1959 Rules, first declared 100 metres around protected monuments as prohibited and a further 200 metres as regulated. Because these zones came from rules and not from the Act itself, they were challenged in courts.
• 2010: Parliament passed the AMASR (Amendment and Validation) Act, 2010 (published on 30 March 2010; most parts treated as in force from 23 January 2010). It wrote the zones into the Act itself and validated (made legal from the start) actions taken since 16 June 1992. That is why the law works retrospectively.

What do Sections 20A, 20B and 20C say?

• Section 20A, prohibited area: the area within 100 metres of a protected monument, in all directions. No new construction is allowed here. The government can declare a wider prohibited area if needed. Existing buildings may be repaired or renovated only with permission.
• Section 20B, regulated area: the area starting where the prohibited area ends and going 200 metres further in all directions (so up to about 300 metres from the monument). Construction, repair or rebuilding here needs permission. The government can declare a larger regulated area by notification.
• Section 20C: lays down how a person can apply for permission to repair or renovate a building in the prohibited area, or to build in the regulated area.

How does permission work, step by step?

1. The owner applies to the competent authority, an officer (not below the rank of Director of Archaeology) notified by the central government.
2. Within 15 days, the competent authority sends the application to the National Monuments Authority (NMA).
3. The NMA studies how the project would affect the monument (its look, safety, and access) and sends its recommendation within two months.
4. The competent authority then grants or refuses permission, as recommended, within one month.
5. Refusal must be in writing, after giving the applicant a hearing, within three months of the application.

Heritage bye-laws

Section 20E requires heritage bye-laws for each protected monument. These are detailed local rules about permitted building height, design of fronts (facades), drainage, roads and service lines near that monument. They are prepared by the competent authority with the help of INTACH (Indian National Trust for Art and Cultural Heritage) or other expert bodies, approved by the NMA, and laid before both Houses of Parliament.

National Monuments Authority (NMA)

Created by Section 20F (inserted in 2010) and set up in 2011 under the Ministry of Culture. It has:

• a whole-time Chairperson, appointed by the President, with expertise in fields like archaeology, town planning, architecture, heritage or conservation;
• up to five whole-time and five part-time members, appointed by the central government on a selection committee's recommendation;
• the Director-General of the ASI as an ex officio member (a member because of the post held). Members serve three years and cannot be reappointed. The NMA also recommends how protected monuments should be graded and classified.

Penalties

After the 2010 amendment, building in a prohibited or regulated area without permission can be punished with imprisonment up to two years, a fine up to ₹1 lakh, or both. Officials who fail to stop such illegal construction can face up to three years in prison, a fine up to ₹1 lakh, or both.

Other key definitions

An "ancient monument" under Section 2 is a structure, monument, cave, rock carving, inscription or similar object of historical, archaeological or artistic interest that has existed for at least 100 years. Under Section 35, the government can declare that a monument is no longer of national importance, and remove it from the protected list.

India's position and Indian examples

• As of August 2025, the ASI looked after 3,685 centrally protected monuments and sites, according to a reply in the Lok Sabha.
• In March 2024, the ASI began the process of removing 18 monuments from the protected list, many of which had been declared "untraceable" (they could no longer be found), such as Kos Minar No. 13 in Haryana. This used Section 35.
• In the Puri Jagannath Temple case (Ardhendu Kumar Das v. State of Odisha, 2022), the Supreme Court held that the Act does not completely bar essential public facilities, such as toilets and drinking water, within the prohibited area.
• State governments protect state-level monuments through their own laws, for example the Karnataka Ancient and Historical Monuments and Archaeological Sites and Remains Act, 1961.

Commonly confused concepts

• Prohibited area vs regulated area: Prohibited = first 100 m, no new construction. Regulated = the next 200 m beyond that, construction allowed only with permission.
• AMASR Act, 1958 vs Antiquities and Art Treasures Act, 1972: AMASR protects monuments and sites (immovable heritage). The 1972 Act controls movable objects like sculptures, coins and paintings: an "antiquity" is generally an object at least 100 years old, and it cannot be exported without permission.
• Centrally protected vs state protected monuments: Centrally protected ones are of national importance and come under the ASI and the AMASR Act (Union List Entry 67). State protected ones come under state archaeology departments and state laws (State List Entry 12).
• ASI vs NMA: The ASI looks after, repairs and digs at monuments. The NMA is a separate statutory body that recommends whether construction near a monument should be allowed.
• Protected monument vs UNESCO World Heritage Site: Protection under AMASR is a national legal status. World Heritage status is an international listing under the 1972 UNESCO Convention. Many World Heritage Sites in India, like the Taj Mahal, are also centrally protected.

Issues, criticism and the way forward

• Fixed distances for every monument: The same 100 m and 200 m apply to a huge fort and a small tomb. A parliamentary Select Committee examining a 2017 amendment bill suggested deciding limits monument by monument, rather than one blanket rule.
• Development vs heritage: The AMASR (Amendment) Bill, 2017 proposed to allow central government public works (like roads and metros) in prohibited areas. It was passed by the Lok Sabha in 2018 but was not passed by the Rajya Sabha, so it did not become law. Governments have since spoken about further changes to the Act.
• Hardship to owners: People who owned land near a monument long before it was protected may be unable to build. The Act has no provision to acquire such land or pay compensation, which owners say is unfair.
• Slow bye-laws and measurement disputes: Heritage bye-laws have been prepared for only some monuments, and disputes over how distances are measured (as in this case) are common.
• Too many minor monuments: Parliamentary panels have said the protected list includes many minor or lost monuments and should be rationalised, while important unprotected sites need attention.
• Way forward: Experts suggest monument-specific zones based on scientific study, quick completion of heritage bye-laws, clear digital maps of every zone, and fair compensation or transfer of development rights for affected owners.

Concepts to Know

• Directive Principles of State Policy (DPSP): Goals in Part IV of the Constitution that the government should follow while making laws. Courts cannot directly enforce them.
• Validation Act: A law passed to make earlier government actions legal from the date they were taken, especially when courts have doubted their legality.
• Retrospective effect: When a law applies to a past period, not only from the date it was passed.
• Encroachment: Illegally occupying or building on land that belongs to someone else or to the public.
• Ex officio member: A person who is a member of a body automatically because of the post they hold.
• Bye-laws: Detailed local rules made under a main law to manage specific matters.
