Junagarh Fort is a fort in the city of Bikaner, Rajasthan, India. The fort was originally called Chintamani and was renamed Junagarh or “Old Fort” in the early 20th century when the ruling family moved to Lalgarh Palace outside the fort limits. It is one of the few major forts in Rajasthan which is not built on a hilltop. The modern city of Bikaner has developed around the fort.
Construction of the walls and associated moat commenced in 1589 and was completed in 1594. It was built outside the original fort of the city (the first fort built by Rao Bikaji), about 1.5 kilometres (0.93 mi) from the city centre. Some remnants of the old fort are preserved near the Lakshmi Narayan temple.
The 5.28 hectares large fort precinct is studded with palaces, temples and pavilions. These buildings depict a composite culture, manifest in the mix of architectural styles.
