Over 25 historical organizations and agencies throughout the county form the "Washtenaw County Historical Consortium" to promote local area history.
The member organizations represent historic homes, farms, depots, mills, churches, schoolhouses,
the Detroit Observatory, museums with historical collections, and two libraries
for historical or genealogical research.
Some attractions do not have regular visiting hours, but most are available
by special appointment for individual or group tours. Those facilities that are
wheelchair accessible are so only on the main floor. Visitors are urged to contact
a site beforehand to confirm all information and learn about special exhibits
