city, Skagit county, northwestern Washington, U.S., on the northern tip of Fidalgo Island. Connected by ferry to the San Juan Islands and Victoria, British Columbia, the city originated in the 1860s as a port called Ship Harbor. Local real estate developer Amos Bowman fancifully renamed it in 1877, giving his wife's maiden name, Anna Curtis, what he thought to be a Spanish spelling. Once known largely for the oil-storage facilities and fish-processing industries that are still an important source of revenue, the city emerged in the 1980s as a tourism and recreation centre. Padilla Bay National Estuarine Sanctuary, a stopover for migrating waterfowl populations, lies just east of the city. Inc. 1891. Pop. (1990) 11,451; (2000) 14,557.
