Hindu architecture developed from crafts passed down from the demigod Visvakarman. Styles include Dravidian found in south India, Gopuram featuring vaulted towers, and Nagara between the Vindhyas and Himalayas. Temples evolved from communities of craftsmen and follow principles in ancient texts, with regional variations. Key components are the Vimana dome above the inner sanctum Garbagriha, the large Gopuram gateway tower, the transitional Antarala space, the rising Shikhara tower, and the outdoor pillared hall Mandapa.
