Bienvenue!  Welcome!  As you view our website, we hope you enjoy learning more about our organization and about Mercer Island's sister city relationship with the lovely city of Thonon-les-Bains, France. We look forward to you attending our events and becoming involved with the Mercer Island Sister City Association.

The Mercer Island Sister City Association is a nonprofit, community based organization promoting educational, cultural and other exchanges between the citizens of Thonon-les-Bains, France and Mercer Island, Washington.  The Mercer Island • Thonon-les-Bains relationship was founded in 2000 and is an association composed of individuals and organizations interested in promoting close ties between both cities.

Thonon-les-Bains, France and Mercer Island, Washington are both lakeside cities located close to major metropolitan areas.  Both have relatively similar sized populations with a focus on education.  Both enjoy a multitude of parks, festivals and gardens.  Both are proud of their pedestrian-oriented town centers, where residents can dine, shop and relax.  Both enjoy the benefits of being close to a major city with national and international events, while maintaining a distinct, small town feel.  These two cities combine to form a perfect match with hopes of a long lasting relationship and partnership.
