Masi Periasamy Temple is a prominent hilltop shrine situated in the Kolli Hills range of Tamil Nadu. It is dedicated to the local deity Periasamy, an ancestral protector figure deeply revered by the mountain tribes and the surrounding farming communities. The temple is reached via a series of stone steps winding through the dense forest landscape of Ariyurnadu. It serves as a central site for regional festivals where followers gather to offer sacrifices and perform traditional rituals. The site is noted for its lack of elaborate Dravidian architecture, focusing instead on rugged, open-air simplicity that reflects its spiritual integration with the mountain environment. Visitors often encounter goats and roosters brought for ritual offerings, reflecting the temple's traditional folk practices.
