Port Townsend is a city in Jefferson County, Washington, United States. The population was 9,113 at the 2010 census.
The bay was originally named "Port Townshend" by Captain George Vancouver (for his friend the Marquis of Townshend) in 1792.The official European-American settlement of the city of the same name took place on April 24, 1851. American Indian tribes located in what is now Jefferson County in the mid-19th century included the Chimakum (or Chemakum), Hoh (a group of the Quileute), Klallam (or Clallam), Quinault and Twana (the Kilcid band — Anglicized: Quilcene).Port Townsend is also called the "City of Dreams" because of the early speculation that the city would be the largest harbor on the west coast of the United States.By the late 19th century, Port Townsend was a well-known seaport, very active and banking on the future. Many homes and buildings were built during that time, with most of the architecture ornate Victorian.
