The
Red Fort or
Lal Qila is a historic fort in the Old Delhi neighbourhood of Delhi, India, that historically served as the main residence of the Mughal emperors. Emperor Shah Jahan commissioned construction of the Red Fort on 12 May 1639, 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. The fort represents the peak in the Mughal architecture under Shah Jahan and combines Persian palace architecture with Indian traditions.
