The Qutb complex is a collection of monuments and buildings from the Delhi Sultanate at Mehrauli in Delhi in India, which were built on the ruins of Lal Kot, which consisted of 27 Sanatan and Jain temples and Qila-Rai-Pithora (Prithviraj Chauhan's city, whom Muhammad Ghori's Afghan armies had earlier defeated and killed in the Second Battle of Tarain).[1] The Qutub Minar in the complex, named after Qutbuddin Bakhtiar Kaki, was built by Qutb-ud-din Aibak, who later became the first Sultan of Delhi of the Mamluk dynasty.
