Situated about 7 km from Annamacharya University, Rajampet, the Mannuru Sivalayam Temple is a revered shrine believed to be established by Sri Adi Shankaracharya in the 8th century CE. He installed a self-manifested Shiva Lingam after performing Sandhyavandanam, marking the site as spiritually powerful. Known for its healing Rudra Abhishekam and tranquil setting, the temple is deeply connected to the Annamayya heritage. It draws pilgrims especially on Mondays and Maha Shivaratri, offering Vedic rituals in a serene natural environment. Preserved by local efforts, it stands as a timeless center of devotion and spiritual renewal.
