Gwalior Fort is an 8th-century hill fort near Gwalior, Madhya Pradesh, central India. The fort consists of a defensive structure and two main palaces, Gurjari Mahal and Man Mandir, built by Man Singh Tomar. The fort has been controlled by a number of different rulers in its history. The Gurjari Mahal palace was built for Queen Mrignayani. It is now an archaeological museum. The oldest record of "zero" in the world was found in a small temple, which is located on the way to the top.
Gujari Mahal was built by Raja Man Singh for his wife Mrignayani, a Gujar princess. She demanded a separate palace for herself with a regular water supply through an aqueduct from the nearby Rai River. The palace has been converted into an archaeological museum. Rare artefacts at the museum include Hindu and Jain sculptures dated to the 1st and 2nd centuries BC
In 1093, the Pal Kachawaha rulers built two temples to Vishnu. The temples are pyramidal in shape, built of red sandstone with several stories of beams and pillars but no arches.The one is small and other is large
