The only shrine dedicated to TRINITY is Thanumalaya's at Suchindram 14 Kms from Kanyakumari. The name Thanumalayan denotes the combination of the Trimurthis Sthanu is a synonym for Siva, Mal for Vishn and Ayan for Brahma. It is believed that the top, middle and base of the Linga in the temple represent Siva, Vishnu and Brahma respectively. Tradition goes that Indra was purified at this place and hence the Suchindram. Suchi means Purity.
The temple here is noted for its exquisite workmenship in stone. It is a treasure houseof sculptures. The musical pillars are very impressive and some of the sculptures in the temple like Vigneshwari, the female form of Vinayaka and the scene of Geethopathesa to parthasarathi in the form of Trinity are rarely to be found elsewhere. Carved exqusitely out of a single block of granite, the imposing figure of Anjaneya, 18 feet height, is a product of marvellous sculptural skill. The gigantic image of Nanjdhi locally known as "Makkalai" made of chank powder is considered one of the biggest in India.
