The red fort of Agra (not to be confused with Red Fort of Delhi), was built by the Mughal emperor Shah Jahan after his ascension to the Mughal throne. An older fortified building called the Badalgarh was located at this site and came under the reign of several northern Indian empires such as the Delhi Sultanate, Afghans, Maratha and the Mughals. Agra fort was also the final resting place of Shah Jahan when he was imprisoned by his son Aurangzeb.
