About Bellevue

With a population of 141,000, Bellevue is the Seattle metro area’s third-largest city. As such, it’s been described in terms like “satellite city”, “edge city”, and “boomburb”. The name Bellevue is French for “beautiful view”, and the nation agrees: Bellevue is regarded as one of the best places to live in America, as well as one of the best cities to start a business in.

Founded in 1869, Bellevue is home to two colleges, a number of diverse neighborhoods, an excellent primary school system, and a variety of cultural events. These include the annual Bellevue Arts and Crafts Fair, which just celebrated its 70th anniversary, and the Strawberry Festival, which the city has hosted since 1925.
