Gwalior Fort, Gwalior

Gwalior Fort in Gwalior, in the central Indian state of Madhya Pradesh, stands on an isolated rock, overlooking the Gwalior town, and contains a number of historic buildings. It is one of the biggest forts in India. From historical records, it is established that it was built in the 8th century. The fortress and the city have been integral to the history of the kingdoms of North India. It is said that the Mughal Emperor Babur (1483–1531) described it as, "The pearl in the necklace of the forts of Hind".

The fort’s history relates to two parts namely, the main fort and the Gurjari Mahal and the Man Mandir palace. The first part was built during the early Tomar rule, while the second part, the Gurjari Mahal (now a Museum) and the palace, was constructed by Raja Man Singh Tomar in the 15th century for his favourite queen, Mrignayani.

Gwalior Fort also occupies a unique place in the human civilization as the place which has the first recorded use of zero ever. Also referred as 'Shunya' in sanskrit, this site is of mathematical interest because of what is written on a tablet recording the establishment of a small 9th century Hindu temple on the eastern side of the plateau (marked by the '0' on the nineteenth century map at the left). By accident, it records the oldest "0" in India for which one can assign a definite date.

History of the fort is indelibly linked to the former kingdom of Gwalior, ruled by several Rajput kings. The earliest dating of the fort is quoted to a publication of the Government of India on Gwalior, which traces it to an inscription of 525 AD in a Sun temple, which is said to have been built by the Hun (Huna) emperor Mihirakula (Sveta Huna ruler in 510 AD during the reign of Huns in India)............
