This huge, beautiful Jain temple is built on Chandragiri hill at Shravanabelagola and dates back to 3rd Century BC. Chavundaraya basadi (red arrow), Chandragupta Basadi (square complex before the pillar), was built by Emperor Ashoka in the 3rd Century BC and is dedicated to Emperor Chandragupta Maurya. The pillar is called Mahasthambha (great pillar). Chandragiri also has memorials to numerous monks who have meditated here since the 5th century AD.
