Mutual Life Building

The Mutual Life Building is a six-story office structure in Pioneer Square distinguished by its red brick facade and stone trim at 605 First Avenue. Built in 1890, it features the solid construction typical of late 19th-century Seattle commercial architecture and was comprehensively updated during the 1980s renovation while preserving its original character.

Built in 1890 on the site of Henry Yesler's original cookhouse, which served as Seattle's first gathering place for the community. The structure became central to the city's preservation movement during the 1960s, ultimately leading to Pioneer Square's designation as a National Historic District in 1970.

This building represents Seattle's commitment to preserving its historic commercial districts and remains a focal point for understanding the city's urban heritage. Visitors can observe how the structure fits into the broader fabric of a neighborhood dedicated to honoring its past.

The building sits in the heart of Pioneer Square where it is easily accessible on foot among other historic structures and local businesses. Visitors are best served by walking through the neighborhood to observe the architecture and street layout that make the district distinctive.

The structure stands on historically significant ground as it marks the location where Henry Yesler's original cookhouse once stood, a place crucial to early Seattle's social life. This connection to the city's founding story is brought to life by the preservation of the building itself.
