One of the most important ancient historic sites in Udaipur is Gangodbhav Kund located in Ahar. It is the most ancient remain of the Ahar civilization.

According to tradition it is considered to be a very sacred place and bathing in its water is supposed to confer as much merit as one gets from bathing in the holy Ganges. It comprises a platform where earlier stood a four columned Chhatri and reservoir of water running round it. Some of the old material used for the repairs of the relics indicates the high standard of the ancient sculpture of Mewar. One of the versions about the antiquity of this Kund is that in the time of Asadity because of his justice and righteousness, the holy river Ganges burst out here in the form of a Kund and so it is considered to be sacred. According to the second version, the river Ganges bubbled up here through the strength of the devotion of a lady who was left here by her father-in-law. According to the third version, it is believed that the Kund is a memorial spot of the pious King Gandharva Sen, father of King Vikramadity Tanwar, who ruled here before the capture of the Ujjain town.

On the walls are studded idols of Shiva-Parvati  Panigrah, Kartikeya riding a peacock, Ganesh, Surya, Brahma etc. There is another Kund in the south with a Shiva temple in the midst. There is another idol of Lord Shiv in the form of a big Lingam on which have been carved a thousand small figures of Lingum.

In memory of the bubbling of the sacred river Ganges, every year on the eleventh day of the bright half of the twelfth month of the Indian calendar i.e. Falgun Shukla Ekadashi, people throng here to take a holy dip in the water of the Kund. On this day, a fair, especially of the Bhil region is held here. On this occasion Bhils of different villages of Mewar assemble here.

The Kund is also the venue of several religious activities such as Pind-daan and Gangoj.
