Tour & Rental Information

Nonprofit Meeting Space

To serve as a community resource, the Washington Trust for Historic Preservation makes the Stimson-Green Mansion available as a free, small-scale meeting space to non-profit organizations who are members of the Washington Trust or who are sponsored by current members. The space most often available for complimentary use is a 20-person meeting room with an attached restroom, known historically as the Turkish Room. This room is in the basement and can be reached via one flight of stairs. The Library, Parlor, and Dining Room may be available upon request and with a rental fee. Please review our nonprofit meeting guidelines for more information and complete the inquiry form for availability and reservations.


The Washington Trust offers regular public tours of the Stimson-Green Mansion and arranges private group and educational tours for students of all ages. Our tours provide insights into the architectural character and interior design features of one of Seattle’s most impressive examples of turn-of the-20th century residential architecture as well as a lively look at the life and times of the Stimson and Green families and their First Hill neighborhood.

Stimson-Green Mansion tours are offered (generally) the fourth Tuesday of each month. The cost is $10 for the general public, but free for Washington Trust members and a guest. (Not a member? Join today!) Please note that our century-old mansion can present challenges in terms of accessibility.

Masks are encouraged but not required. Tour groups will be limited to 20 attendees. Sign up for the following tour dates:
