The Washington Trust for Historic Preservation is pleased to offer public tours of our landmark Seattle headquarters, the Stimson-Green Mansion, built 1899-1901. Members of the public can tour this stately residence on the corner of Minor Avenue and Seneca Street on Seattle's First Hill, the city's premier residential enclave from the 1890s through the first decades of the 1900s. 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. We invite you to take this opportunity to visit one of the four historic homes that remain out of the forty or more large and prestigious homes that once graced the neighborhood.

The historic mansion tours are offered the second Tuesday of each month from 1:00 to 2:30 p.m. The cost is $10 for the general public but free for Washington Trust members and a guest. Space is limited to 25 people per tour, and pre-registration is required. If less than five people are registered, tours may be cancelled. Private group tours may also be arranged at a mutually convenient time. Please note that our century-old mansion can present challenges in terms of accessibility.
