Located in a valley of rugged red sandstone, surrounding the Agastya Lake, Badami was formerly called Vatapi. It is an archaeological delight owing to its beautifully crafted sandstone cave temples, fortresses and carvings. Badami Chalukyas had this place as its capital between 540 CE and 757 CE. This place is quite popular for its cave temples that are cut out of sandstone rocks which surrounds the Agastya Lake. Three among the four cave temples are dedicated to deities of Hinduism and one temple is dedicated to Jainism. The Government of India has declared Badami as one of the heritage cities in India. Agastya Theertha, a serene lake is a must-see attraction in Badami. The Bhootnath Temple which faces the Agastya Lake was built in the 5th Century CE.
