Gazi Kalu Champabati Mazar Sharif is located in historical Barobazar of Kaliganj Upazila of Jhenaidah District. Gazi, Kalu and Champavati were among the spiritual saints who came to spread Islam in Barobazar. There are several legends about the identity of Gazi, Kalu and Champavati.
Legend has it that Barkhan Gazi was the son of Darvesh Shah Sikander, the ruler of Birat Nagar, and Kalu was Sikander's foster son. Barkhan Gazi initiated Hindus and Buddhists into Islam by passing through Sundarbans from Sylhet to Gazi. Their social and religious status stood in the way of Gazi's love affair with Champavati, daughter of Chappainagar feudal king Ramachandra aka Kutut Raja. The crown king ordered his general Dakshina Raya to discipline Ghazi and Kalu. Commander Dakshina Roy was defeated in the war and converted to Islam. King Ramachandra was defeated by Gazi's followers and took Champavati to Baribathan, his main home in Jhenaidah.
Later, after many battles of Raja Ramchandra with the followers of Gazi, Gazi rescued Champavati and returned to Barobazar and they breathed their last in Barobazar. Among the three shrines eight feet tall on the southern bank of Sri Ram Raja's fenced lake, the middle one is Gazi's, the western one is Kalur's and the eastern one is known as Champavati's. Apart from this, near Gazi Kalu Champavati shrine there is the shrine of General Dakshina Roy.
Many films, Pala songs, stage plays have been composed on Ghazi, Kalu and Champavati. There are 6 small banyan trees around the shrine. Many people tie the oldest big banyan trees like polythene threads of different colors to fulfill their vows. The lovers write their wishes on small pieces of paper and tie them to the tree. In 1992, on the initiative of the district administration, these three graves were tied together and a wall was built around them and tin sheds were built for the servants. People of all communities irrespective of Hindus, Muslims come to offer vows at Gazi Kalu Champavati Shrine.
