Explain the significance of the Qutub Minar as a historical monument.

The Qutub Minar is a significant historical monument built by Qutubuddin Aibak and completed by Iltutmish in 1220 CE. It was started in 1199 CE and dedicated to the Sufi saint Qutub-ud-din Bakhtiyar Kaki. It is world-famous for its great height and architectural design, standing 72.5 metres tall, making it the tallest brick minaret in the world.

The minar has five storeys that taper as they ascend, with a base diameter of 14.3 metres narrowing to 2.7 metres at the top. It is constructed using red sandstone, marble, and grey quartzite. The structure features verses from the Holy Quran, intricate carvings, and floral motifs. According to Lane-Poole, its jutting balconies, alternating fluting, and fine Arabic inscriptions highlight its beauty and craftsmanship. It is considered an architectural marvel that every visitor to Delhi should see.
