Bala Quila also known Alwar fort is a fort in Alwar in Indian state of Rajasthan. It is situated on a hill in the Aravalli Range, above the town of Alwar. The fort is 5 kilometres (3.1 mi) long and is about 1.5 kilometres (0.93 mi) wide. It was built in 15th century by the Hasan Khan Mewati. In the following centuries it went to the Marathas, Yadavas,and to the Kachwaha Rajputs.
Hindu scriptures (the Puranas), dictate that 'a fort is the strength of a king'. Within the fort are 15 large and 51 small towers perched on the ridgetop, 340 metres (1,120 ft) above the city. The fort included 446 openings for musketry, along with 8 huge bastions encompassing it. When visited a few years ago, this fort was being used by the Police as a radio listening post. Visitors may initially be made very uncomfortably unwelcome and threatened with fines for even coming to the fort but it is only 20 rupees or so, which then grants access. The ruins must have been magnificent in their time but now most roofs are gone plus many of the floors and there are trees growing in the main rooms.
The fort is accessible by both bikes and cars.
