Non-Mormons are welcomed to tour this building - the first and oldest Tabernacle in the faith. The original architect was Mitt Romeney's great, great, great grandfather. There are 2 truly beautiful spiral staircases up to the balcony. Lots of interesting details if you are interested in architecture. Glass windows imported from NY, shipped to San Francisco and transported overland to the building site. Well worth an hour or so. Friendly tour guildes.
