Gwalior Fort

Gwalior Fort sits on a 105-metre sandstone hill 3 km long that dominates Gwalior city. The fort has been continuously occupied for at least 1,000 years — passing in succession through the Tomars, Mughals, Marathas (Scindias), and the British. The most architecturally distinguished addition is the Man Singh Palace, built 1486–1516 by Tomar king Man Singh — a turquoise-and-yellow tiled exterior that anticipates Rajput palace architecture by a century. Inside the fort: the Saas-Bahu Temples (11th-century Vishnu temples with extraordinary vertical carving), the Teli ka Mandir (a 9th-century Pratihara-period Vishnu temple, the tallest pre-Mughal structure on the hill), and the Chaturbhuj Temple. The latter holds an inscription from 876 CE that contains the earliest unambiguous use of zero (0) as a number in any Indian inscription — a foundational artefact of mathematics history. The fort museum, the Sahasrabahu Mandir reliefs, and the British-era Scindia school within the fort are bonus stops.
