What drives Friday Harbor’s History grade
On its age, its old homes and the National Register, Friday Harbor is more historic than 76% of U.S. towns, #18 of 285 in Washington. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
A−
HistoryA character grade: shown, never part of Friday Harbor’s overall grade.
Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Friday Harbor’s 22.0 sits above most of its state (91% of Washington towns have fewer) while its 6 historic buildings outnumber those of 72% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1845.

Timeline
Friday Harbor, 1845 to 1972
Woven from the archive, old maps, post office records, the National Register and the people born here.
In 1845 the Hudson's Bay Company laid claim to San Juan Island. In 1850 they built a salmon curing station. A few years later they started a sheep farm.
The town's name originates from Joseph Poalie Friday, a native Hawaiian. Friday worked at the Puget Sound Agricultural Company's Fort Cowlitz, from 1841 to 1859–60 and later moved north to San Juan Island, raising and herding sheep around the harbor.
After the peaceful settlement obtained following the Pig War, the San Juan Islands became a separate county in 1873. Friday Harbor was named the county seat. Friday Harbor was officially incorporated on February 10, 1909. It remains the only incorporated town in the San Juan Islands.
