Indian Art and Architecture is a concept encompassing the visual and structural heritage of the subcontinent, reflecting its diverse religious and cultural history from antiquity to the modern era. Its origin traces back to the Indus Valley Civilization (c. 3200 to 2000 B.C.), followed by the rise of stone architecture during the Mauryan period (c. 321-184 B.C.), which saw the construction of Stupas and monolithic Pillars under Emperor Ashoka. The Gupta era (after A.D. 400) marked the emergence of free-standing temples and the development of painting as a distinct art form.
The mechanism for classifying Hindu temple architecture involves three primary styles: Nagara, Dravida, and Vesara. The Nagara Style, prevalent in North India from the 5th century, is characterized by a curvilinear tower called the Shikhara and is often built on an elevated stone platform. The Dravida Style, which developed from the 7th century in South India, features a compound wall, a stepped pyramid-shaped tower known as the Vimana, and massive entrance gateways called Gopurams. The Vesara Style is a hybrid blend, mainly found in the Deccan, combining elements of both.
The preservation of this heritage connects directly to the Ancient Monuments and Archaeological Sites and Remains Act, 1958 (AMASR Act), an Act of Parliament that provides for the preservation of monuments of national importance and regulates archaeological excavations. The Archaeological Survey of India (ASI), established in 1861, is the principal organization operating under this Act. The AMASR Act, 1958, was significantly amended by the Ancient Monuments and Archaeological Sites and Remains (Amendment and Validation) Act, 2010. This amendment formalized the protection regime, stipulating that the area up to 100 metres from a protected monument is a prohibited area, and an additional 200 metres is a regulated area for construction activities. The National Monuments Authority (NMA), a statutory body established in 2011, also functions under this post-2010 framework.
