Constructing the Indian Heritage

The Indian capital city of Delhi and the northern Indian states have numerous stone structures that feature “Alwar Quartzite” as a primary building material. Particularly in Delhi, a number of structures constructed between the late nineteenth century British Raj era and the “pre-Sultanate period” (eleventh century or earlier) made considerable use of Alwar Quartzite as the primary building material.It is clear from the ashlar masonry in the British Barracks in Delhi to the usage of Alwar Quartzite as rubble masonry in the fortification of well-known forts like the Purana Qila and the Tughlaqabad Fort. Alwar Quartzite, which is readily available in the area, was widely used during the Islamic era to build tombs, mosques, victory towers, and other structures inside the boundaries of the Qutb Complex and Humayun’s Tomb Complex, two well-known UNESCO World Heritage sites. For the fortification of Amer, Jaigarh, Nahargarh, Bhangarh, Moti Dungri, and several other forts in the northeastern region of the Rajasthan State, Alwar Quartzite was an equally desired building material by several Hindu monarchs. Alwar Quartzite’s strength and durability, together with its abundance and local availability, have made it an obvious option for the primary building stone in many architectural monuments throughout North India’s various civilizations and kingdoms.
