Construction commenced in 1193 under the orders of India's first Muslim ruler Qutb-ud-din Aibak, and the topmost storey of the minaret was completed in 1386 by Firuz Shah Tughluq. The Qutb Minar is notable for being one of the earliest and most prominent examples of Indo-Islamic architecture.

It is surrounded by several other ancient and medieval structures and ruins, collectively known as Qutb complex. The complex is listed as a UNESCO World Heritage Site. It is one of the most popular tourist destinations in Delhi, and was also India's most visited monument in 2006, as it attracted 3.9 million visitors, even more than the Taj Mahal, which drew about 2.5 million visitors

The Qutab Minar is tall, with 379 steps leading to the top. The diameter of the base is 14.3 meters, while the top floor measures 2.75 meters in diameter. Surrounding the building are many fine examples of Indian artwork from the time it was built in 1193. A second tower was in construction and planned to be taller than the Qutb Minar itself. Its construction ended abruptly when it was about 12 meters tall. The name of this tower is given as Alai Minar and construction of recent studies shows that this structure has been tilted in one direction. It is made of red sandstone all the way except for two stories at the top. This part is of white marble and was made by Firoz Shah Tughlaq. He had decided to put a prominent finish to the magnificent minar.
