This unusual temple is natural monolith carved cave temple dedicated to Lord Shiva. On the 14 / 15 January every year a ray of light passes precisely through the horns of the Nandi bull and illuminates the deity inside. This unique phenomenon occurs every year on the Makar Sankranti day and attracts large number of devotees. The precision of the event displays the advanced technical and scientific knowledge of those who built the temple. The architecture of this temple combines 'Vastukala' with astronomy.
