As the Muslim rulers ruled the South India, it was then brought under the control of the Nawab of Cuddapah.

It is located on the left bank of river Penna on the route to Badvel from Kadapa at a distance of about 25 km.

[3][4] It was said that this place used to be inhabited by people who wanted to meditate in the sereneness of climate and had a thick canopy of Indian Banyan trees which served as shades for them.

In Sanskrit, Sidda means people who perform meditation and vata is the Indian Banyan tree.

[3] Siddavatam Fort was constructed by Matti Raja, a Tuluva dynasty feudatory chief to the Vijayanagara Empire, in 1303 CE.

[6] The fort houses an ancillary passage which allows the visitors to gain access even after the closure of the main gates.

The fort here was much developed under the rule of king Varadha Raju, who is the son-in-law of Sri Krishna Deva Raya.

Later Aurangzeb's commander Mir Jumla II in 1682 along with shah nawaz khan captured Siddavatam along with other places in the region.

There is also a 16 pillar Mantapam built in the name of Bhakara Panthulu, who also lends his name to the nearby hamlet of Bhakarapeta.
