The Willamette Historic District has been designated as a national historic district by the National Register of Historic Places. It will be listed as the Willamette Falls National Historic District. This is the result of a 2.5 year effort by the City of West Linn, the Historic Resources Advisory Board, the Willamette Neighborhood Assoication, and many dedicated citizens. The national district includes most of the properties included by the locally designated Willamette Historic District. Eventually a road sign on I-205 will direct tourists to this neighborhood.
A historic district is an area or neighborhood that has a concentration of buildings and associated landscape and streetscape features (50 years or older) that retains a high degree of historic character and integrity, and represents an important aspect of a city's history.
