The full guide

MOHAI, Seattle's Museum of History and Industry, tells the story of Seattle and Puget Sound inside the restored Naval Reserve Armory at 860 Terry Ave N in Lake Union Park, South Lake Union. Come for the 1919 Boeing B-1 hanging in the atrium, the giant neon Rainier "R," the True Northwest history galleries and a working submarine periscope looking over Lake Union, and plan around the free admission to core exhibits on the first Thursday of every month from 5 to 8 p.m.

It is an easy pairing with a walk around Lake Union Park, a stop at the Center for Wooden Boats next door and lunch in South Lake Union, all a short ride from downtown on the streetcar.

What's Inside MOHAI

The Grand Atrium

Walk in to the Faye G. Allen Grand Atrium, where the restoration uncovered the armory's original floor and ceiling. Look up to see the 1919 Boeing B-1, the first commercial plane built by Bill Boeing, hung as if on a flight path onto Lake Union, where it once took off and landed. At the south end, a three-story grid of Seattle icons includes the neon Rainier "R" sign, and at the north end rises Wawona, a 64-foot sculpture by John Grade built from timber salvaged from an 1897 schooner, as described in the museum's history.

True Northwest: The Seattle Journey

Ringing most of the second floor, MOHAI's core exhibit walks you through the region's story in 22 sections, from the era before pioneer settlement up to the modern day. Look for the Petticoat Flag, a US flag sewn by women during the 1856 Battle of Seattle, among the keynote objects.

Maritime Seattle

Climb to the top floor for the maritime gallery, a room first built as a replica ship's bridge to train naval recruits during World War II. The star is a working World War II-era submarine periscope that gives you a 360-degree view of Lake Union and downtown.

Bezos Center for Innovation and Kid-Struction Zone

The Bezos Center for Innovation, which opened in 2013 in part of the Grand Atrium, adds a newer gallery to the museum, and families with young children can head for the Kid-Struction Zone, designed for kids aged 2 to 7 and their caregivers, with giant foam bricks, a magnetic ball-and-pipe board and a reading corner. MOHAI also rotates temporary exhibits through its Walker Gallery, so check the MOHAI visit page for what is on now.

A Short History of MOHAI

The museum grew out of the Seattle Historical Society, founded in 1914 after Morgan and Emily Carkeek's Founder's Day gatherings, and opened its first museum in Montlake in 1952. When the rebuilding of State Route 520 forced a move, MOHAI restored the Naval Reserve Armory on Lake Union in a $90 million campaign and opened its new home on December 29, 2012. Today it is the largest private heritage organization in Washington, with a collection of nearly four million artifacts, photographs and archival items, and it is a Smithsonian affiliate.
