The Sioux City Masonic Temple in Sioux City, Iowa was built during 1921–1922. It was listed on the National Register of Historic Places in 2004.
It is a two and a half or three story building that cost nearly $300,000 to build, not including nearly $200,000 of custom furnishings. In 2004 it was deemed significant as "an excellent, unaltered example of the Spanish Colonial Revival architectural design"; it was one of only two downtown commercial buildings in that style, which was popular during 1915 to 1940. The other is the NRHP-listed Sioux City Free Public Library, two blocks south. It was designed by Sioux City architects Beuttler and Arnold.[1]
