In 1955, the Michigan Legislature, by passage of Public Act 10, authorized markers to be displayed at historic sites as approved by the Michigan Historical Commission. Today, historical markers are located throughout the state and mark various historical sites. They are intended not only to mark the site, but also to provide the residents of Michigan with an understanding of our rich history. Governor Williams, at the April 2, 1957, dedication of the Capitol marker noted: "When people understand their history, there is a better opportunity to project the future."
The original Capitol marker was replaced with the present marker during the 1979 centennial of the Capitol. The marker briefly notes the history of the State's three Capitols and construction of the present Capitol.
