Capt. John C. Ainsworth House

The Capt. John C. Ainsworth House features a distinctive two-story portico design and incorporates elements of classical Greek architectural principles throughout its structure.

Built in 1851, this residence belonged to John C. Ainsworth, the founder of Oregon Steam Navigation Company, which revolutionized maritime transportation in the Pacific Northwest.

The house represents mid-19th century architectural preferences of successful business leaders in the American Pacific Northwest during the territorial expansion period.
