CC Madhya 9.17

nṛsiṁha dekhiyā tāṅre kaila nati-stuti
siddhavaṭa gelā yāhāṅ mūrti sītāpati
Word for word: 
nṛsiṁha dekhiyā — after seeing the Lord Nṛsiṁha Deity; tāṅre — unto Him; kaila — did; nati-stuti — offering of various prayers; siddhavaṭa — to Siddhavaṭa; gelā — He went; yāhāṅ — where; mūrti — the Deity; sītā-pati — Lord Rāmacandra.
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.
