Cumorah
Cumorah, more commonly known among Mormons as the Hill Cumorah, is the name given to a hill in Palmyra, New York. It was in this hill, in roughly the year AD 421, that the prophet/historian Moroni deposited a record, engraved upon golden plates, he and his father Mormon had made. Fourteen hundred years later in 1827, that same Moroni directed young Joseph Smith to retrieve the record from the Hill Cumorah. Joseph did as directed and translated the plates into the Book of Mormon.
In addition to being a storehouse to the sacred record, the Hill Cumorah was somewhat of a school for young Joseph. During the four years between Moroni's first visit to the prophet and the time Joseph was allowed to take the plates, Joseph annually visited Cumorah. Each year, Moroni would meet Joseph and give him further knowledge and instruction.
