Standing 72.5 meters tall, Qutub Minar is the world’s tallest brick minaret and a symbol of Mamluk Dynasty in India. Its design, influenced by the Minaret of Jam in Afghanistan, seamlessly blends Afghan and indigenous architectural styles, marking a significant historical transition. Constructed primarily in red and buff sandstone, the minar tapers from a 14.32-meter base to a 2.75-meter top, featuring five distinct storeys. Commissioned by Qutbu'd-Din Aibak in 1199 AD, the first storey is adorned with Kufic inscriptions praising Muhammad Ghori. Iltutmish, Aibak’s son-in-law, completes the next three storeys by 1236, while Firoz Shah Tughlaq reconstructs the final two storeys in white marble in 1368 after lightning damage, creating a striking polychromatic effect.

Chakraborty offers a window into the architecture of the minar, showcasing its exterior decorated with alternating angular and rounded flutings and balconies resting on intricate muqarnas corbels. The surface features elaborate carvings of Arabic inscriptions and geometric motifs typical of Saracenic design, with Thuluth script calligraphy adding to its grandeur. Within the Qutub complex lies the Quwwat-ul-Islam mosque, the first mosque in Northern India. The Alai-Darwaza, added by Alauddin Khalji in 1311, introduces Islamic ornamentation techniques to Indian architecture. This UNESCO World Heritage Site stands as a testament to the ingenuity of medieval Islamic architects.
