The Ellora Caves in Maharashtra are a UNESCO World Heritage site featuring 34 caves carved out of a basalt cliff. These caves represent three major religions: 12 Buddhist caves (earliest, 6th-7th century), 17 Hindu caves (middle period, 7th-8th century), and 5 Jain caves (latest period, 9th-10th century). This unique coexistence showcases India's ancient religious harmony and architectural evolution.
