Located in Sioux City, Iowa, the First Congregational Church stands as an architectural rarity—one of only a handful of churches designed in the Prairie School style. Built between 1916 and 1918 by architect William L. Steele, fresh from his collaboration with George Grant Elmslie on the Woodbury County Courthouse, the structure emphasizes horizontal lines through Roman brick and crisp rectilinear forms characteristic of the Prairie style. Its design incorporates eclectic touches, most notably a distinctive dome and prominent round-headed windows that set it apart from the typically domeless Prairie aesthetic. The church replaced an earlier Congregational building that burned in 1916; the original congregation had been established in Sioux City in 1857. After the congregation relocated in 1966, the building passed through successive religious communities, most recently serving as Iglesia Evangelica Pentecostes Principe de Paz. Listed on the National Register of Historic Places in 1979, the structure has been flagged by preservation groups as requiring extensive restoration.
