Red Fort [SEP] Introduction
The Red Fort is a historic fort in the city of Delhi (in Old Delhi) in India that served as the main residence of the Mughal Emperors. Emperor Shah Jahan commissioned construction of the Red Fort on 12 May 1638, when he decided to shift his capital from Agra to Delhi. Originally red and white, its design is credited to architect Ustad Ahmad Lahori, who also constructed the Taj Mahal. It was constructed between May 1639 and April 1648. On 15 August 1947, the first prime minister of India, Jawaharlal Nehru, raised the Indian national flag above the Lahori Gate.
