The restoration of a massive 11th-century Trikuta temple in the Nizamabad district of Telangana has led to a fascinating technological discovery. Engineers found a network of terracotta-lined subterranean pipes designed to circulate cool air and water beneath the temple's sanctum. This ancient climate-control system highlights the advanced engineering of the Kalyani Chalukya architects.
The project is currently focusing on reassembling the triple-shrine layout using traditional lime mortar and stone-locking techniques. The discovery of these cooling channels has prompted a new study into the thermal management used in medieval Indian sacred architecture. The site also features intricate star-shaped platforms and pillars depicting rare floral and geometric motifs.
