Located about 9 km from Annamacharya University, Rajampet, Sri Udayagiri Yellamma Devasthanam in Mannur is a sacred temple dedicated to Goddess Yellamma (Renuka Devi). Nearly 500 years ago, traders from Mannur brought her idol from Udayagiri, and when their bullock cart halted mysteriously at a spot in the village, it was seen as divine will to establish the temple there. Built in traditional South Indian style, the temple is a hub for daily worship and vibrant annual festivals featuring processions, annadanam, and cultural events. It stands as a beacon of heritage, community devotion, and spiritual continuity.
