Agra Fort This remnant of the Mughal era made of red sandstone is Agra's most spectacular building except the Taj. Emperor Akbar started building it in 1565 along the Yamuna River's banks, and his grandson Shah Jahan later added white marble decorations. During his rule, what had been a vast military castle was changed into a palace. The fort's size will be what most impresses you. The walls occasionally reach a height of 20 metres across its 2.5 kilometre diameter. The interior is just as spectacular as the exterior once you enter. The Shish Mahal (mirror palace), Khas Mahal, Diwan-e- khaas (hall of secret hearings), Moti Masjid (pearl mosque), and Nagina Masjid (gem/jewel mosque) are just a few of the magnificent buildings you can find here. To get the most out of your visit, my recommendation is to meander around the numerous buildings for a whole morning or afternoon. Opening Hours: 7am – 6pm Entry Fee: 100 Rs. for foreigners, 20 Rs for Indians
