Replete with ancient tradition, Adoni is home to a number of Ganesha temples. Local legends suggest that if water levels reached the belly of the idol that guards the temple, then the flood would vanquish the entire city. With a history of flooding, at an elevation of just 430 meters, the city has undergone a number of cultural and physical changes in recent centuries. The most well known site in the city includes the Ranmandala Hill, which houses the Lord Hanuman Temple. Nearby, the Ramjala Lake plays a crucial role in Hindu mythology, and it is claimed that the lake was formed by an arrow shot by Rama into the ground in order to provide water for the goddess Sita during Aranya Vaasa. The lake’s direct tributary is the Tungabhadra River, which provides drinking water for the town, and also serves as a tourist attraction with its munificent water birds. With a rich cultural history, the city’s physical geography reflects unique elements of Hindu influence over the span of generations.

One of the most famous and historical well, which is popularly known as Venkanna Bavi, a biggest well located in the heart of the town. It is commonly popularized story in respect of the said Venkanna Bavi is that around 400 years ago, there was a Minister in the kingdom, Shri Venkanna, who wanted to provide permanent drinking water facility to the town people, planned for a right sight of water by engineers, and constructed this huge well, but even after digging such a huge well, the water point was not found. While the things stood thus, while he was in deep sleep, he dreamt and god advised him to give 'Bali' (sacrifice) of a pregnant woman, then the water will come up. Then he thought that instead of giving some third person's Bali, "let me give 'Bali' of my own daughter-in-law", and made it so, and immediately there was severe pressure of water found. It is believed that since he gave the 'Bali' of a pregnant woman, the abandon water in the well is of no use because it is too salty, and cannot be used, so till now the well is no use to the public. But the structure, construction of well using only stones and not by using any cement anywhere in the entire structure, is worth seeing. Of late, the Venkanna Bavi became death spot for suicides. The local authorities now restricted the easy access of the public to the well, to avoid the suicides.
