Known as the Red Fort of Agra, this walled imperial city was founded in 1565 by the Emperor Akbar (1556-1605) and is a well-deserving UNESCO World Heritage site, located just 2.5 kilometres from the famous Taj Mahal. Its palaces, grand mosques and elaborate public hall are crafted from pink-red sandstone and are testament to an era when Indo-Muslim art, strongly marked by influences from Persia, was at its height. Emperor Shah Jahan, who built the Taj Mahal for his deceased wife, was imprisoned by his son Aurangzeb in Agra Fort. He is said to have died in the Musamman Burj, a marble tower he himself built, with one of the most alluring views of the Taj Mahal.
