The Vijayanagara Empire originated in the Deccan Plateau region in the early 14th century. It was established in 1336 by Harihara Raya I and his brother Bukka Raya I of the Sangama Dynasty. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit, while Carnatic music evolved into its current form. During the Vijayanagara Empire, the Pemmasani Nayaks controlled parts of Andhra Pradesh and had large mercenary armies that were the vanguard of the Vijayanagara Empire in the sixteenth century. The Lepakshi group of monuments are culturally and archaeologically significant as it is the location of shrines dedicated to Shiva, Vishnu, and Veerabhadra which were built during the Vijayanagara Kings' period (1336–1646). The temples are the location of mural paintings of the Vijayanagara kings, Dravidian art, and inscriptions. Near the temple complex is a large granite Nandi bull. On a hillock known as "Kurma Saila" ('tortoise-shaped hill') are other temples to Papanatheswara, Raghunatha, Srirama, and Durga.
