CC Madhya 9.17
siddhavaṭa gelā yāhāṅ mūrti sītāpati
Upon seeing the Ahovala-nṛsiṁha Deity, Caitanya Mahāprabhu offered many prayers unto the Lord. He then went to Siddhavaṭa, where He saw the Deity of Rāmacandra, the Lord of Sītādevī.
Siddhavaṭa, also known as Sidhauṭa, is ten miles east of the village of Kuḍāpā. Previously this place was also known as the southern Benares. There is a great banyan tree there, and it is therefore known as Siddhavaṭa. Vaṭa means banyan tree.
