Maynard Building, Romanesque Revival office building in Pioneer Square, Seattle, United States

The Maynard Building is a five-story masonry office building at 119 First Avenue South in Pioneer Square, Seattle. Designed by Albert Wickersham in the Romanesque Revival style, it has rounded arches, decorative columns, and ornate carvings across its facade.

Albert Wickersham designed the five-story masonry building, completed in 1892 as the Dexter Horton Building, where Dexter Horton's bank grew into Seafirst Bank. It stands on the site of an earlier Dexter Horton Building, from whose steps Governor Watson Squire's martial law decree was read during the 1886 Seattle riot to "yells and howls of defiance." The building was refurbished between 1974 and 1975.

The building's name honours David "Doc" Maynard, the physician and early Seattle settler for whom the city's Maynard Avenue is also named. Its earlier identity survives in local memory as the Dexter Horton Building, after the banker whose enterprise became Seafirst Bank. The address, 119 First Avenue South, places it in the Pioneer Square historic district.

The building sits on First Avenue South and is easy to reach, with access to the surrounding Pioneer Square neighborhood streets. A thorough renovation in the 1970s modernized the interiors while preserving the historical features of the facade.

The building stands on the site of an earlier Dexter Horton Building, from whose steps Governor Watson Squire's martial law decree was read during the Seattle riot of 1886, answered by "yells and howls of defiance" from the crowd. The present structure, finished in 1892, replaced it.
