We invite you to visit our History Center & Museum located at 40 Wilbur Street. It’s housed in the City of Lake Oswego’s last remaining Iron Company Worker’s Cottage. The circa 1880 building is the oldest house in Lake Oswego that is open to the public. Admission is free! We invite you to watch local television coverage of the museum, and find out about the museum on TripAdvisor.

“We will probably be judged not by the monuments we build but by those we have destroyed.”—New York Times editorial

A message from our founder:

My vision was to create an organization to advocate for the triple bottom line benefits—social, economic, and environmental—of preserving our unique built heritage as well as having a strong, researched-based focus on education. In the relatively brief time since founding the non-profit Lake Oswego Preservation Society in 2011, hard work, meticulous research, creative thinking, vision, and land use advocacy along with dedicated volunteers, generous members, granting organizations, and other supporters and friends have contributed to realizing this goal. May our current community, and future Lake Oswego citizens, enjoy the fruits of all of our labors on behalf of the place that we love. 

— Marylou Colver
