The Angel Moroni (pronounced /mɒˈroʊnaɪ/) is an angel that Joseph Smith, Jr. claimed visited him on numerous occasions, beginning on September 21, 1823. The angel was the guardian of the golden plates, which Smith said were buried in a hill near his home in western New York, and which he said were the source material for the Book of Mormon. Moroni is an important figure in the theology of the Latter Day Saint movement, and is featured prominently in Mormon architecture and art. Three Witnesses besides Joseph Smith said they saw Moroni in 1829 visions, as did several other witnesses who each said they had their own vision.
