Lord Alarnath temple is situated in Brahmagiri. The temple is just around 25 km from Lord Jagannath Temple, Puri odisha. When the public darshan of the Lord Jagannath in the main temple at Puri remain closed for a fortnight for Anavasara, lakhs of devotees visit to the Alarnath temple at Brahmagiri. Anavasara is the two weeks period when Lord Jagannatha takes rest in isolation from the rest of the world after suffering from fever due to the annual bathing festival called debasnana purnima. It is a small temple. Lord Alarnath is a four-armed Vishnu deity with Sankha, Chakra, Gadha and Padma.
During Anavasara period Mahaprabhu Chaitanya visited puri but could not see Lord Jagannath. As he was disappointed but Lord Jagannath give the Indication to visit Lord Alarnath temple. On his visit he was praying god on a stone and that stone kept inside the temple and called as prema- sila.
