The Parmaras of Abu were a branch of the Paramara dynasty, who ruled parts of southern Rajasthan, especially the Mount Abu region.
Their ancient capital was Chandrawati, located near Mount Abu.
Chandrawati was an important center before being overshadowed by later powers and towns like Sirohi.

Sirohi – Later capital of the Chauhans in the region, not of the Parmaras of Abu.
Bhinmal – An ancient town, historically associated with the Gurjara-Pratihara dynasty.
Shivganj – A nearby town, but not the capital of the Parmaras.
