Who built the Red fort in Delhi, India?

The Red Fort was built by the Mughal Emperor Shah Jahan in Old Delhi that served as the capital of the Mughals until 1857. For nearly 200 years, it was the centre of Shah Jahan’s empire where he led a life known of great pomp and ceremony. He would make public appearances, called ‘darshan’, from a large balcony, receive public petitions in the Diwan-I-Am, review important state matters with his principal ministers in the Diwan-I-Khas, discuss the most secret affairs with his kin and most trusted officers in the Royal Tower or Shah Burj, hold lively gatherings and feasts, and then retire to his bedchambers for the night. This fort was the greatest of Mughal palaces and was the heart of Shah Jahan’s empire.
