Gurramkonda fort was believed to be constructed by the Nawab Abdul Nabi Khan in the year 1714 C.E., after the fall of Vijayanagara kingdom and remained one of the principal Muslim strongholds.  Tippu Sultan occupied this fort from Kuman-ud-Dim, son of Mir Ali Raza Khan in 1782 C.E.  Later it went into the hands of the Nizam under the Treaty of Srirangapatnam in 1792.

            Inside these fortifications can be seen Rangini Mahal, Hanuman temple, temple for Vishnu, tanks, Mosque and Granary etc.  The fortification consists of Lower, middle and the upper. The fortification was constructed only on three sides viz. south, east and west while the north side is being impregnable secured by the natural huge perpendicular barren hillock.  All these three fortifications are irregular in plan.  The lower fort has 20 bastions with intervals and covering an area of 1,680 m with only one entrance gateway on the southern side.  The central fort has 13 bastions with intervals and covering an area of 1,270 mtr.  The upper fort is on the summit of the hillock and consists of pillared mandapa, barracks and other ancient buildings for garrison.  In the fort wall there are parapets with battlements and with splayed openings built in brick masonry. 

            Among the building within the lower fort  the Rangini Mahal deserves attention for its good workmanship. There is an inscription of on a slab of Banas and a sculpture of Mahishamardhini within the building.
