Agra Fort is located in Agra, India. The fort is also known as Lal Qila, Fort Rouge and Red Fort of Agra. It is about 2.5 km northwest of its much more famous sister monument, the Taj Mahal. The fort can be more accurately described as a walled palatial city.

By most estimates, the fort was taken over from the Lodis by the Mughals in the late 16th century, by Akbar the Great. During his reign, he shifted the government of his empire from Delhi to Agra. Because of this, much of Agra flourished and the site of the old Lodis fort began changing into more of a royal estate. Akbar tended to build from red sandstone, often inlaid with white marble and intricate decorations.

It was only during the reign of Akbar's grandson, Shah Jahan, that the site finally took on its current state. The legend is that Shah Jahan built the beautiful Taj Mahal for his wife. Unlike his grandfather, Shah Jahan tended to have buildings made from white marble, often inlaid with gold or semi-precious gems. He destroyed some of the earlier buildings inside the fort in order to make his own.

At the end of his life, Shah Jahan was imprisoned by his son, Aurangzeb, in the fort, a punishment which might not seem so harsh, considering the luxury of the fort. It is rumored that Shah Jahan died in Muasamman Burj, a tower with a marble balcony with an excellent view of the Taj Mahal.

This was also a site of one of the battles during the Indian rebellion of 1857, which caused the end of the British East India Company's rule in India, and led to a century of direct rule of India by Britain.
