The temple is believed to have been constructed sometime around the 12th century, although the exact date is unknown. There is an ant-hill representing the presiding deity inside the temple premises and because the temple is open for only one week every year, it is considered special to obtain a darshan during the Deepavali festival.The temple is unusual in that it is open to the devotees only for a week every year. For the remainder of the year, the Goddess is left with a lit lamp, flowers, water and two bags of rice as an offering until the next year. The nandaa deepa, (a ghee-lit lamp) burns for the entire duration of the temple closure, with the ghee never depleting. The anna naivedya (the rice offering) offered to the devi (goddess) at the time of closing the temple is warm and unspoiled when the doors are opened again, a year later. It is revered as a great temple in Hassan.. 🌟Archeological experts consider the Hasanamba Temple to be an example of the epitome of temple architecture in Karnataka. The city of Hassan dates to the 11th century and the temples around Hassan signify the various dynasties that have ruled ever since the 11th century. It was originally built by the Hoysala dynasty in their tradition, reflecting their faith in Jainism. The temples in the Hassan district are some of the examples of the Hoysala tradition of temple architecture.
