Amravati River
Amravati river (Maithili: अमरावती नदी) is a legendary former river in the Mithila region of the Indian subcontinent. In the ancient period, it was flowing through the village of Sarisab Pahi. The archaeologists involved in the exploration of the river have estimated it to be more than 4000 years old. According to legend, the river existed in Ramayana during the journey of Lord Rama in Mithila. During the period of King Nanyadeva of Karnat Dynasty in Mithila, a city named Amravati was also established near the bank of the river. In the early times, many rivers flowing in the Mithila region either dried up or merged over time. The Amravati river is one which dried up over a time in the early days. Presently in the Isapur village of the Madhubani district, the remains of the path of flow of the legendary Amravati river still exists. It is believed to be the origin place of the Amravati river. According to the archaeologists, the remains of ancient civilization have been found in the Isapur village.
In the ancient times when the Amravati river was live and water was flowing in it, then Sarisab Pahi used to be a major trading center. The trading centre of Sarisab Pahi was called Hate Bazaar. Presently that place is known as Hati. On the eastern bank of the river there were two tols namely Thatheri Tol and Darji Tol. These two locations are presently situated in the western panchayat of the Sarisab Pahi village. There is a Hindu temple known as Siddheshwar Nath Mahadev Mandir on the bank of the river. It is said that the merchants used to worship here daily before starting their business.
