31 yrs after tragedy, Qutub Minar's doors remain shut ...The Qutub Minar, a UNESCO World Heritage Site, is a towering minaret in Delhi, India, known for its intricate architecture and historical significance. Its construction began in 1192 by Qutb-ud-din Aibak, the first Muslim ruler of Delhi, and was later completed by his successor Shamsuddin Iltutmish and then further renovated by Firoz Shah Tughlaq. Early Construction and Purpose: Qutb-ud-din Aibak initiated the construction in 1192, after the defeat of Delhi's last Hindu kingdom. The initial purpose was likely as a victory tower and a minaret (a tall tower used by a muezzin to call Muslims to prayer). Aibak only completed the first story before his death. Further Development: Shamsuddin Iltutmish, Aibak's successor, added three more stories to the minaret. The topmost story suffered damage from lightning and was reconstructed by Firoz Shah Tughlaq, who also added a fifth story. Restorations and Modifications: The Qutub Minar has been repaired and restored several times throughout history, including by Firoz Shah Tughlaq and Sikandar Lodi. Major Robert Smith, a British officer, undertook repairs in the 19th century. Sher Shah Suri also added an entrance to the structure. Key Features: The minaret is 72.5 meters (238 feet) tall and tapers from a 14.32-meter base to a 2.75-meter summit. It is constructed of red sandstone and marble, with intricate carvings and inscriptions in Arabic and Nagari script. The Qutub complex also includes the Quwwat-ul-Islam Mosque, the Alai Darwaza, and the tomb of Iltutmish. Inscriptions and Symbolism: The inscriptions on the minaret provide historical details and reveal its construction history. While some believe it was a victory tower, others suggest it served as a minaret for calling out prayers. The structure is a symbol of Delhi's rich history and architectural prowess. UNESCO Recognition: The Qutub Minar is a UNESCO World Heritage Site, recognized for its cultural and historical significance. The Archaeological Survey of India (ASI) manages and protects the monument.
