Thanks to the generous donation of the Stimson-Green Mansion by Patsy Bullitt Collins in 2001, the Washington Trust is proud owner and steward of one of the most significant residential landmarks in Seattle. The Mansion is primarily of Tudor and Gothic revival, but its eclectic styles also range through Moorish, Romanesque, Neoclassical, and Renaissance influences.


The Stimson-Green Mansion is one of Seattle's premier wedding and special event venues. In addition, the Mansion is a great location for photo shoots of all types. Kaspar Special Events & Catering is the exclusive caterer for special events at the Mansion. Please visit their website for details and information, and call 206-298-0123 or email to rent the Mansion for your next event!
