There are some locations that are presented to us on a platter, as in the director takes the pains to show the name of the place as part of the song sequence. The song below is one such instance where there are 2 locations where the song has been filmed primarily and the Chandragiri fort is just one of them. The other one is the popular shore temple in Mahabalipuram and we will get to that another day.

About the location (from Wiki):

In 1646 the fort was annexed to the Golkonda territory and subsequently came under Mysore rule. It went into oblivion from 1792 onward.
