The Agra Fort (Qila Agra) is a historical fort in the city of Agra, and also known as Agra's Red Fort. Mughal emperor Humayun was crowned at this fort in 1530. It was later renovated by the Mughal emperor Akbar from 1565 and the present-day structure was completed in 1573. It served as the main residence of the rulers of the Mughal dynasty until 1638, when the capital was shifted from Agra to Delhi. It was also known as the "Lal-Qila" or "Qila-i-Akbari" .
Before being captured by the British, the last Indian rulers to have occupied it were the Marathas. In 1983, the Agra fort was inscribed as a UNESCO World Heritage Site because of its importance during the Mughal Dynasty. It is about 2.5 kilometers (1.6 mi) northwest of its more famous sister monument, the Taj Mahal. The fort can be more accurately described as a walled city. It was later renovated by Shah Jahan.
