During a major preservation project of an 11th-century Western Chalukya Shiva temple in Karnataka's Koppal district, conservationists have discovered a series of 'shadow-dampening' pillars. These architectural features were designed to prevent the casting of shadows across the central deity during specific ritual hours, a technique previously unrecorded in medieval Indian temple engineering.
Experts from the Archaeological Survey of India (ASI) believe these pillars were part of a sophisticated astronomical alignment system. By carefully angling the stone facets, the ancient architects ensured that the inner sanctum remained perfectly illuminated by ambient light without harsh shadows, creating a serene environment for Vedic rituals and meditation.
