The Michigan Historical Marker program is administered by the State Historic Preservation Office and is one of the largest frivately funded historical marker programs in the nation with over 2,500 sites identified and nearly 1,600 markers constructed.
In 1988, Jim Brennan began visiting these markers with the objective of photographing each one. Almost 20 years later, his Michigan Markers web site has photographs about 1500 markers and has text for even more. The site offers an amazing look at the history of Michigan, with photos, the text of the markers, location and maps. As an added bonus, the site is searchable by topic and county!
