Sivasailam (Sivasaailam per the Indian census)[1] is a village located on the bank of River Gadananathi River in Tenkasi taluk, Tenkasi district, Tamil Nadu, India.

During the month of Chitirai (mid April) to Puratasi (mid October) wind from the mountains blows gently and rain sprinkles and makes the place cool.

The main God of the temple is Sivasailanathar (a form of God Shiva) and his consort is Goddess Paramakalyani Amman, a form of Goddess Parvathi Amma.

There are many stone inscriptions inside and near the temple and all are written in "Old Tamil."

The Stone Inscription tells that the Jamindars of Ambur, Alwarkurichi, Kadayam, Krishnapuram and Poovankurichi are responsible for collecting the tax from people and giving to the temple.
