Dhanushadham is a municipality district and an important pilgrimage of Mithila Culture and Hindu Religion. The municipality was established on 19th May 2014 by merging the existing Dhanushadham, Dhanusha Govindpur, Umaprempur and Yagyabhumi village development committees. In ancient days, King Janak started ploughing his farm field by himself to minimize food insecurity in his kingdom, Mithila. One child girl came out of land while he was cutting furrows in the soil and turning it up with help of plough, later she was named as Sita.
Sita, daughter of King Janak lifted the Lord Shiva’s bow and cleaned entire house. Sita (also known as Janaki) was the 2nd human being to lift the Lord Shiva’s Bow (Dhanush), King Janak was the 1st. King Janak wanted his son in law to be brave enough to handle the bow, so, he announced a festival requesting presence of entire prince and kings of neighboring kingdoms. The person to lift the Lord Shiva’s bow had to be selected as bridegroom for Goddess Sita in the festival. Prince Ram son of King Dashrath from Ayodhya (presently situated in India) was the only successful person to lift the bow. Not only did he lift the bow, he also put arrow (van) on it. The heavy weighted bow was broken into three pieces while putting arrow on it. One piece of the bow went to heaven, second fell to hell (via Dhanush Sagar/pond situated in Janakpur) and middle part landed on the earth.
The place where middle part was landed is named as Dhanushadham. The part of the bow is secure in Dhanush temple. Yearly around 10 Lakh religious tourists are visiting the temple to see the live object of the Lord Shiva’s bow.
It is believed that the object like Bow/ Dhanush seen in different Sagar/Ponds of Janakpurdham is the same piece which was fallen in Dhanush Sagar and went to hell.
