The Taj Mahal.
It is located about 2.5 km northwest of the Taj Mahal. It is the most important fort in India. The great Mughals Babur, Humayun, Akbar, Jehangir, Shah Jahan and Aurangzeb lived here, and the country was governed from here. At the end of his life, Shah Jahan, who built the famous Taj Mahal, was imprisoned by his son, Aurangzeb, in the fort. It is rumored that Shah Jahan stayed in Muasamman Burj, a tower with a marble balcony with an excellent view of the Taj Mahal, watching his wife tomb every day, and died there. What's a love story!
