A systematic excavation at the ancient pilgrimage site of Naimisharanya in Uttar Pradesh has uncovered a series of geometrically complex brick fire-altars (Vedi) dating to roughly 900 BCE. The layout of these altars conforms precisely to the dimensions specified in the early Shulba Sutras, providing rare physical evidence for the practice of early Vedic rituals.
The site also yielded a collection of gray-ware pottery and iron ritual implements. This finding reinforces the historical continuity of Naimisharanya as a major center for Sanatan spiritual learning and suggests that the transition from late-Vedic to early-historic urbanism in the Gangetic plain was marked by high levels of mathematical and architectural standardization.
