Beyond Biswanath Chariali, towards south, there is Biswanath Ghat, also called popularly as "Gupta Kashi". The town is named after the ancient Biswanath mandir. It is called Gupta Kashi, in comparison with Kashi during the golden rule of the Guptas apart from this there is one more believe that since Banasur had built this place secretly from Lord Shiva to surprise Him, that is why it is known as Gupta(In Assamese Gupta means secretly) Kashi. Going by popular sayings, Kashi was home to temple of 330 million gods. The ghat has a cluster of temples of different gods. A Siva temple also called Pani Biswanath is located at the confluence of Bridhaganga (Burigonga) river with Brahmaputra. But now what is left is just the stone posts, beams and other ruins. During the summer the temple remains under water. Only in winter worship is done by constructing temporary shed which draws lot of tourists. On the third day of Assamese Bihu a mela is held at a place called Pani Bharal. The deity is taken from Biswnath Ghat to this place for a day and returns to Ghat there. The mela is celebrated to commemorate the Guxai Bihu festival. Another Siva temple was built in higher ground. But it submerged under ground during the great earthquake of 1897. It could only be partly raised by engineers. The current Biswanath temple had been built in lieu of it. One can visit from here the island of Umatumuni, an archaeologically famous place. Then there is the Siva dol in reverence of God Siva, built by Ban, the king of Tezpur of Hari Harar Yudha fame. The problem of infiltration by Bangladeshis is a major concern over here. Most of the villages consists of people belong to scheduled castes. If you plan to visit Gupta Kashi, it is recommended that you stay in Biswanath Chariali city.
