Siddhavatam is a village in Kadapa district of the Indian state of Andhra Pradesh. It is located in Siddavatam mandal of Kadapa revenue division. This village was initially under the rule of Matli Kings. As the Muslim rulers ruled the South India, it was then brought under the control of the Nawab of Cuddapah. With the advent of British, it was ceded to them by the Nawab. Under the rule of British, Siddavatam served as the headquarters of the district briefly. Currently the city of Cuddapah serves as the headquarters and Siddavatam was reduced to a Mandal in the district. Geography

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. Hence, the name Siddavatam is said to be a portmanteau of two words Sidda + vatam. History

Siddavatam Fort was constructed by Matti Raja, a Tuluva dynasty feudatory chief to the Vijayanagara Empire, in 1303 CE. It lies on the banks of the Pennar River. The fort extends over an area of . Visitors can view gateways and decorated pillars at the two ends of the fort. Top of the fort has been adorned with carvings of Gajalakshmi. It is noteworthy that the 17  bastions which once used to protect the region are still visible in the fort. The fort houses an ancillary passage which allows the visitors to gain access even after the closure of the main gates. It is considered as the gateway to Dakshina Kashi. The temples and masjid present inside its premise include the Ranganatha Swamy Temple. The fort here was much developed under the rule of king Varadha Raju, who is the son-in-law of Sri Krishna Deva Raya. This fort was just a mud fort at the time the area was ruled by "Matli Rajulu". Later it came under the control of Varadha Raju. Earlier it was a part of Udayagiri Kingdom. Matli Yellama Raju used to support the second Venkatapathi Rayalu in many wars. For this favour, Siddavatam was given to Matli Yellama Raju as a gift along with some other places. Later Matli Anantha Raju remodelled the fort as Rock Fort. Later Aurangzeb's commander Mir Jumla II in 1682 along with shah nawaz khan captured Siddavatam along with other places in the region. Later Aarkatu Nawabs occupied the town. In 1714 Abdul Nabi Khan, who was ruling Kadapa conquered Siddavatam. This place was also ruled by Mayana Nawabs for some period. In 1799, it went into the hands of British East India Company. From 1807 to 1812 Siddavatam was the district headquarters. However, since it is on the bank of river Penna, every time there was a flood, the place was marooned from other places of the district giving rise to administerial difficulties and subsequently the district headquarters was shifted to Kadapa.
