Overview
Petersburg is a small city in western Monroe County, about 17 miles west of Monroe and the same distance east of Adrian. Richard Peters settled the area as early as 1824 and became the first postmaster when the Summerfield post office opened in 1831. In 1836, Monroe natives Thomas Cole and Austin Wing formally laid out the community on land bought from Peters. The post office was renamed Petersburgh in 1863, and the spelling was shortened to Petersburg in 1893. The community incorporated as a village in 1869 and as a city in 1967. At 0.49 square miles, it is the second-smallest city by land area in Michigan, and the River Raisin forms part of its northwest edge. City Hall and the Summerfield–Petersburg Library stand along Center Street downtown.
