Sri Moolastaneswara Swamy Temple in the Mulapeta neighbourhood is considered the oldest Sri Shaiva shrine in the Nellore area. The main deity is Lord Shiva in the form of Moolastaneswara, and the temple is associated with the Shaiva saint Appayya Dikshitar who is said to have visited and composed verses here in the 16th century.
The temple architecture shows layers of different periods — the original 11th-century core surrounded by later additions and gopurams added during the Vijayanagara period. Less visited than the Thalpagiri Ranganath Swami Temple, which means a quieter experience. Pilgrims come primarily on Shivaratri and on Mondays; other times it is calm and accessible.
