The Joseph Smith Memorial Building is named in honor of Joseph Smith, Jr., the founder of the Latter Day Saint movement. It is located on the corner of Main Street and South Temple in Salt Lake City. Previously the Hotel Utah, it is now an administrative building. On January 3, 1978, it was added to the National Register of Historic Places as the Hotel Utah.
The Church of Jesus Christ of Latter-day Saints now uses this building as follows:
- A large, historical, ornately decorated multi-story lobby, featuring a large white statue of Joseph Smith, Jr, and an enormous crystal chandelier. Live classical music is often performed here as background.
- The FamilySearch center, where the public can use the provided computers and materials to do family history research and genealogy.
- The Legacy Theater, where the public can enjoy inspirational regularly scheduled free showings of various church-produced movies, including Joseph Smith: Prophet of the Restoration.
- Two restaurants, The Roof and The Garden, on the top floor, provide views of downtown Salt Lake City.
- Interior levels of the building are devoted to ongoing work on various Church software projects, supporting the worldwide family history centers, and various other activities.
- Many rooms on the ground level, and on the ninth and tenth floors, can be rented out for wedding receptions or dinners.
- There is a chapel used for the Sunday services of various downtown wards.
- A pair of peregrine falcons returns yearly to nest in a nest box at the top of the building, which has two webcams installed in it, viewable to the public.
