This geological wonder is about 1 km from the Temple. Called as 'Eprochian Unconformity' this geological arch is about 25 feet in length and 10 feet in height and is one of the oldest natural arches in the world. Silathoranam is a natural rock formation in the form of an arch, near the Chakra Tirtham. Geologists have identified the rocks on the hill as pre-Cambrian, and this arch formation suggests an antiquity of several million years to the Tirumala hill
