Sherman City was platted in 1870 and boomed with the increase in local lumber trade. The Sherman City Union Church was built in 1871 as the "Guard of American Revolution Hall." A tornado in 1878 leveled most of the town, but this building survived. In 1898, the building was refitted as a nondenomination church, and served in that function and as a social gathering place. Lumbering declined in the early 1900s, and the rown began declining. The church was abandoned in about 1960, but was rescued and refurbished in 1977-78 by local citizens.
The Sherman City Union Church is a 1-1/2 story frame structure covered with clapboard. A two-story tower at the front has a pyramidal belfry and houses a double-door entrance. The sides have unusual triangular topped narrow windows, and pressed tin covers the interior walls and ceiling.
