The Champapur Digambar Jain Mandir dedicated to Vasupujya, the 12th Tirthankara is located in Nathnagar of Bhagalpur city and happens to be an ancient and Historical Teerth Kshetra. It is believed that al the five Kalyanakas of Vasupujya Tirthankara took place in Champapur itself. Champapur is said to have been the capital of the Anga Kingdom ruled by Karna, the sixth Pandava. The Main temple of Champapur is believed to be about 2500 years, adorned with five altars symbolising the Five Kalyanaka. There are two spectacular ‘Columns of Fame’ that have survived among the four that existed on each corner of the compound. The most recent addition to the sculptures is the 31 feet tall statue of Vasupujya that was built under the guidance of a Charitable trust based in Nagaland.
