This street, which was created in 1936, was named after Alki Point. Alki Avenue SW runs southwest from Duwamish Head to about 450 feet northeast of the point, where it turns south for a block and then becomes Beach Drive SW; Point Place continues another 200 or so feet toward Alki Point.

Alki Point Lighthouse, May 4, 2011. The first light here was supposedly hung in the 1870s; the U.S. Lighthouse Board installed an official one in 1887. The present lighthouse was built in 1913 and automated in 1984. Access is from Alki Avenue SW rather than Point Place SW.

Arthur Armstrong Denny (1822–1899), the leader of the Denny Party that landed at Alki Point on November 13, 1851, helped build this cabin. Most of the party moved to what is now Pioneer Square the next spring. Photograph by Frank LaRoche, no date (though no later than 1891, when the cabin, shown here in ruins, was demolished).
