Vasireddy Venkatadri Naidu, King of Chintapalli and later Dharanikota, was a great devotee of Amareswara. He expanded and renovated the temple. The popular legend has it that once during the course of putting down a rebellion in his land the King had to have recourse to a massacre of the Chenchus, whereupon he lost his mental peace, which he regained only when he came to Amaravati.
He shifted his place from Chintapalli to Amaravati in 1796, and devoted his entire life, time and revenues to building temples for Lord Siva. He renovated the Amareswaraswamy temple here, engaged nine learned archakas for the daily archana of the Lord, and provided them with all the needs of livelihood, including 12 acres (49,000 m2) of land to each. The temple as it stands owes much to him.
