The Saint George Temple is the oldest operating temple in Utah. It is also has the most sealing rooms in all of the temples; however, not all are currently active. This also is the first temple that performed endowments by proxy.
The temple site was locating on swampy ground, so the pioneers loaded the ground with volcanic rock from an old Mexican War cannon. This relic is on display in the visitors' center.
While in the Saint George temple, the Founding Fathers of the United States of America appeared twice to Wilford Woodruff, asking why their work had not yet been performed.
