Welcome to the
Jonathan Clark House
Museum

The Jonathan Clark House, located at the corner of Bonniwell and Cedarburg Roads in Mequon, Wisconsin, is a unique architectural and historical treasure that is being preserved for use by the Mequon-Thiensville community and beyond. The house was built in 1848 and was home to Jonathan and Mary Clark, their eight children and two hired men. It was not only their home but also served as a community meeting place during a time when early settlers such as Clark, his father-in-law Peter Turck and neighbor William Bonniwell were developing the government of the township. The Friends of Jonathan Clark House is a 501c3 organization with volunteers who provide fy ascinating historic events and awesome tours to be enjoyed by the whole family!
