Oregon History, Trompe-l'œil mural in downtown Portland, United States

Oregon History is a pair of eight-story-tall trompe-l'œil murals by Richard Haas, painted on two sides of the Sovereign Hotel outside the Oregon Historical Society. The 1989–1990 works depict John Jacob Astor, wagon trains, and Lewis and Clark Expedition figures including Meriwether Lewis, William Clark, Sacagawea and her child, York, and the dog Seaman.

The Oregon Historical Society commissioned Richard Haas to paint the murals in 1989 for $225,000. They were completed in 1990. After the society sold the Sovereign Hotel in 2014, the 2016 renovation agreement required the murals to be restored; they were painted out and then repainted that summer, and the copies were dedicated in May 2017.

The figures are drawn from the expedition of 1804–1806: Meriwether Lewis, William Clark, Sacagawea carrying her infant son, the enslaved man York, and Seaman, the Newfoundland dog. John Jacob Astor, founder of Astoria, appears alongside wagon trains of overland settlers.

The mural is clearly visible from street level and can be viewed for free from the sidewalk. It is worth viewing the artwork from different positions along the street to fully appreciate the perspective effects.

Artist Richard Haas used optical illusions to create three-dimensional effects that shift depending on your viewing angle. This trompe-l'oeil technique makes the mural an interactive artwork that changes as you move around different corners.
