Qutab-ud-din Aibak, founder of the first of the five dynasties known as the Delhi Sultanate, built this earliest surviving Islamic structure in India. Located about 9 miles south of Connaught Place in Delhi, construction of this tower was started in 1199. It was completed by another Muslim king, Iltutmish. Made of sandstone, its fluted form narrows at the top. This tower (minar) is 238 feet tall and consists of five progressively shorter stories that are separated by balconies. Inscriptions from the Quran are inlaid in the stone to form bands of intricate designs. In front of the imposing structure is an iron pillar and beside it is a mosque. It is commonly believed that Qutab Minar set the tone for Islamic architecture in India.
