Designed by Walter Wilder and Harry White, the Washington State Capitol Building was completed in 1928. Architect Ernest Flagg laid the foundations in 1893, but work was stalled and did not resume until 1922, under a new team and with a new design. Despite criticism that the building was too costly and ornate, construction was completed after six years and seven million dollars. The building is the tallest self-supporting masonry dome in North America, and the fifth-tallest in the world.

Washington became an official territory of the United States in 1853, with Olympia designated as its capital. That same year, Olympia’s founder Edmund Sylvester donated 12 acres of land to the territorial legislature, to be used as the site of the capitol building. Over the next several decades, the government outgrew the two-story wooden structure that served as the original capitol. In 1893, the state announced a competition that called for designs for a new capitol building. 

The winner of the competition was a New York architect named Ernest Flagg, a relative of Cornelius Vanderbilt. Flagg built a basement and laid the foundation of the building, but construction was halted due to the Panic of 1893. In 1901, the state purchased the nearby Thurston County Courthouse and repurposed it as the capitol building (it is now the Office of Superintendent of Public Instruction). Realizing that this building was also too small, the state held another design competition in 1911. This time, the winners were Walter Wilder and Harry White, with the stipulation that Flagg’s earlier foundations still be used. 

Wilder and White did not just design one structure, but an entire campus that was meant to contain six different government buildings. Other notable sites on the capitol campus include the Temple of Justice and the Governor's Mansion, and the landscaping was designed by the famous Olmsted Brothers. Partly inspired by the United States Capitol in Washington, D.C., the Legislative Building became the centerpiece of the campus and the main Capitol Building. When it was completed in 1928, its masonry dome was the fourth-tallest of its kind in the world, behind such iconic cathedrals as St. Peter’s in Rome, St. Paul’s in London, and Santa Maria del Fiore in Florence.

The Capitol Building took six years to build and cost approximately $7.3 million, a price tag that Washington's Governor Roland Hartley railed against at the time. It contains marble from Alaska, Italy, Germany, and France, as well as the largest collection of Tiffany bronze in the world (including a 10,000 pound chandelier that hangs beneath the dome). Washington’s entry as the 42nd state in 1889 is represented by the 42 steps on the staircase at the North Portico. Major earthquakes in 1949, 1965, and 2001 all led to substantial seismic retrofitting, among other improvements.
