The successors of his lineage constructed the present Bobbili Fort following their improved economic conditions in the middle of the 19th century.

The existing fort covers an area of 10 acres (4.0 ha) and was built by Chinna Ranga Rao after he regained his kingdom which was improved upon by his successors in the mid-19th century.

The fort complex has an impressive entrance gate in Indo-Sarcenic architectural style with high dome and many mantapas, Durbar Hall, four major palaces and two temples.

[1] The history of Bobbili can be traced to 1652, when Sher Muhammad Khan, Fouzdar of the Nawab of Srikakulam under the Nizam, had come to the Vizianagaram district.

The then French General Charles Bussy leased Chicacole and Rajahmundry circles to Pedda Viziarama Raju, the Maharaja of Vizianagaram.

[3] On account of the rivalry between the chiefs of Bobbili and Vizianagaram, in 1756 there was a rebellion among the local chieftains which necessitated strong military measures.

The Raja of Vizianagaram, happy with his victory in the hard-fought battle, rejoiced by entering the Bobbili city and hoisted the Flag of France.

Two years later, in 1759, they were offered their old holdings in the presence of colonel Forde (representative of the British authorities in Bengal[10]) by Ananda Raju of Vizayanagaram at Masulipatam.

[10] In the middle of the 19th century, successors of this lineage constructed the present Bobbili Fort, following their improved economic conditions.

[6] Chinna Ranga Rao had built the oldest part of the main palace with its Saracenic arches supporting the first level.

[10] However, in 1861 in a report submitted by the Acting District Engineer to the Chief Secretary to the British Government at Saint George it was said that the stone fort at Bobbili did not have adequate defense capability.

[6] Within the fort complex, there are two temples: one is dedicated to the family deity of the Venugopala Swamy and was built at the time of founding of Bobbili; another one was erected by Chinna Ranga Rao in the aftermath of the war, after he regained his territory.

After this, the image of the Venugopala Swamy is kept at the Dola Yatra Mandapa on the shores of the lake for one day and then moved back to the main shrine.

Opposite to this palace is the Prangmahal, the residence of the Raja, which is very well preserved and decorated with elegant "tapestry, paintings and porcelain" brought from many countries.
