On January 14th every year something extraordinary happens in Bangalore's Gavi Gangadhareswara temple. On that day a ray of sunlight passes through an arch between the horns of stone bull, that stands outside the temple, and lights up the idol inside. It is a phenomenon that is proof of the technical excellence of ancient architects, of their knowledge of astronomy combined with great architectural skill.

The temple itself is dedicated to Lord Shiva and is a natural cave, carved out of a monolithic stone.
