The Architecture of Delhi dates back more than a thousand years. As the capital of several great empires of India, including Rajput kingdom , Delhi Sultanate , Mughal Empire , and British Raj , the city of Delhi has been a centre for art and architecture. The Delhi Sultanate ruled the city between 1206 and 1526. Their rule saw the development of early Indo-Islamic architecture , the most prominent being the Qutb Minar complex , a group of monuments surrounding the Qutb Minar . This period also saw building of many forts and cities like Siri Fort , Tughlaqabad and Feroz Shah Kotla . Many tombs were built around this period which are still present in many locations like Qutb Minar complex, Hauz Khas Complex and Lodi Gardens .
