The Red Fort is situated in Delhi depicts the Mughal architectural brilliance. It was the main residence of the emperors of the Mughal dynasty for nearly 200 years, until 1857. Constructed in 1639 by the fifth Mughal Emperor Shah Jahan. The Red Fort is known for its massive enclosing walls of red sandstone and is adjacent to the older Salimgarh Fort, built by Islam Shah Suri in 1546. The fort complex is considered to represent the zenith of Mughal creativity under Shah Jahan, and although the palace was planned according to Islamic prototypes, each pavilion contains architectural elements typical of Mughal buildings that reflect a fusion of Timurid and Persian traditions. The Red Fort’s innovative architectural style, including its garden design, influenced later buildings and gardens in Delhi, Rajasthan, Punjab, Kashmir, Braj, Rohilkhand and elsewhere.
Every year on the Independence day of India (15 August), the Prime Minister hoists the Indian "tricolour flag" at the main gate of the fort and delivers a nationally-broadcast speech from its ramparts. The holiday is observed throughout India with flag-hoisting ceremonies, parades and cultural events. There is a national holiday, and schools and government offices distribute sweets, but no official work is done."
