The temple contains five distinct natural springs (theerthams) that flow year-round from the hill surface.
According to local belief, these springs were created by Lord Rama to perform penance and cleanse himself after the battle with Ravana.
The temple architecture includes carved stone mandapams and inscriptions that date back to the Chola and Pandya dynasties.
The site serves as a vital hydrological location, as the water from the springs is channeled into irrigation for the foothills below.
The main lingam in the sanctum is believed to be a Swayambhu, meaning it manifested itself rather than being installed by human hands.
Arulmigu Theerthagiriswarar Temple is a historic cave temple situated on the slopes of the Theerthamalai hills in the Dharmapuri district of Tamil Nadu. The temple is dedicated to Lord Shiva, who is worshipped here as Theerthagiriswarar. It is renowned for its five natural springs, known as Theerthams, which are considered sacred by devotees. The structure features rock-cut architecture characteristic of the region's ancient temple building traditions.

Wear sturdy, non-slip footwear as the stone paths near the springs can become slippery.
Carry a refillable water bottle, but respect the sanctity of the five holy springs by only collecting water in designated areas.
Plan for a steady uphill walk, as the temple is built into the side of the hill.
Avoid visiting during the intense afternoon heat, as the stone steps and temple surfaces can reach very high temperatures.
The temple may experience high footfall and specific ritual closures during the Tamil month of Panguni (March-April) for the annual festival.
Remove footwear before entering the temple complex; dress modestly in clothing that covers shoulders and knees; refrain from photography inside the sanctum sanctorum.
