What makes Qutub Minar historically important?
The Qutub Minar is a 72.5-meter tower of red sandstone and marble in south Delhi, begun in 1193 by Qutb-ud-din Aibak to mark the beginning of Muslim rule in India. It is the tallest brick minaret in the world, its five distinct storeys built by successive sultans over 175 years, each reflecting a different ruler's architectural taste. The surrounding Qutub Complex, a UNESCO World Heritage Site, holds the Iron Pillar, a 4th-century column of near-pure wrought iron that has resisted corrosion for over 1,600 years, as well as the Quwwat-ul-Islam, the first mosque built in India, and the stump of the unfinished Alai Minar, an abandoned attempt to build a tower twice the height of the Qutub. A guide decodes the Arabic inscriptions carved into the tower, explains the metallurgical mystery behind the Iron Pillar's resistance to rust, and traces the layers of Hindu, Jain, and Islamic architecture visible in the mosque's repurposed temple columns.
