The Swaminarayan Mandirs in Houston and Chicago are the first temples built in North America all out of stone in the traditional, North Indian architectural style, designed according to the instructions of ancient scriptures and fully adorned with the fine sculpture of skilled craftsmen. The only comparable project in the US is the San Marga Iraivan Temple, an all-granite temple of South Indian, Chola style, currently being built at Hinduism Today's headquarters from stones that are hand-carved in Bangalore and shipped to Hawaii. Both the Houston and Chicago BAPS temples have plans for facilities which will provide visitors with a thorough, interactive, audio-visual introduction to Hinduism and the organization's emphasis on service and volunteerism.
