Mount Pleasant Downtown Historic District, Historic district in Mount Pleasant, United States.

Mount Pleasant Downtown Historic District is centered on the intersection of Broadway and Main and covers eight blocks with 70 buildings from the 1870s to the 1950s. Most are one- or two-story Italianate and Commercial brick commercial blocks, with a few three-story buildings and examples of Late Victorian, Art Deco and International Style. The 1877 Fancher Block at 101-103 E. Broadway is the oldest; the 1920 Broadway Theater retains a 1930s projecting Art Deco marquee.

Mount Pleasant was founded in 1860 as the seat of Isabella County, and its first store opened only in 1864. A fire in 1875 destroyed nearly the whole downtown, and rebuilding switched from frame construction to brick; a second fire in 1882 led to the construction of a fire station. Water and electricity arrived in the 1880s, and the town became a city in 1889.

The district's name comes from its role as Mount Pleasant's commercial core, centred on Broadway and Main. Two theatres carry Art Deco design: the 1920 Broadway Theater, with a projecting marquee added in the 1930s, and the 1937 Ward Theater on South Main, whose facade is finished in porcelain enamel. The Upton Opera House at 200 East Broadway later housed the Isabella County State Bank.

The district centres on the Broadway and Main intersection and covers the surrounding eight blocks, bounded roughly by Mosher, Franklin, Illinois and Washington Streets. Streets were later paved in asphalt and the sidewalks redesigned with planters, benches and historic light posts. Look for the 1930s projecting Art Deco marquee on the 1920 Broadway Theater.

The 1877 Fancher Block at 101-103 East Broadway is the district's oldest building and keeps its original architectural features, unlike the Doughty and Carr and Granger Blocks at 100-108 East Broadway, whose Italianate facades were later obscured by additions. The 1879 building at 130 South Main and the row from 205 to 217 South Main are also singled out as architecturally significant.
