Thanumalayan Temple, also known as Sthanumalayan Temple, is a revered Hindu shrine located in Suchindram, near Kanyakumari in Tamil Nadu. This ancient temple is unique because it is dedicated to the Trimurti — Shiva (Sthanu), Vishnu (Mal), and Brahma (Ayan) — all worshipped in a single sanctum, symbolizing the unity of the three supreme deities.

The temple is renowned for its magnificent Dravidian architecture, intricately carved stone pillars, and the impressive 22-foot-tall musical pillars that produce distinct musical notes when tapped. The gopuram (tower), standing over 40 meters high and adorned with exquisite sculptures, is a striking example of South Indian craftsmanship.
