Between 1911 and 1987, this building served as the world-renowned Hotel Utah. Since renovated and converted into offices, meeting spaces, restaurants (www.diningattemplesquare.com), and reception areas (very popular for wedding receptions), the architectural details have been lovingly restored. The lobby retains its art-glass ceiling and massive marble pillars -- it's worth a stop for a peek inside. The FamilySearch Center (tel. 801/240-4085) has 100 computers and a staff to help you discover your family's roots. A big-screen 500-seat theater (tel. 801/240-4383) offers free showings of an hour-long movie about the life of LDS founder Joseph Smith. Allow between a half-hour to an hour and a half.
