Dunthorpe is an affluent, unincorporated suburb of Portland, Oregon, United States. It is located just south of the Portland city limits and north of the Multnomah County line on the west side of the Willamette River. Lewis & Clark College, Tryon Creek State Park, and Lake Oswego are nearby.


In January 1916, William M. Ladd's Ladd Estate Company purchased 215 acres (0.87 km2) from the soon to be dissolved Oregon Iron & Steel Company for $1. The company drafted very specific provisions for the Dunthorpe development, including: Only residential buildings were allowed, except for outbuildings to house domestic animals; Swine and goats were prohibited; The minimum cost of a house was $3000; and the sale of "intoxicating liquor" was prohibited.

Arts and culture

Museums and other points of interest

One of the notable attractions of the area is the Elk Rock Gardens of the Bishop's Close, an estate which consists of 13 acres (53,000 m2) on a high bluff on the western bank of the Willamette River. The property includes approximately 6 acres (2.4 ha) of cultivated English-style gardens that were designed by the New York firm of Olmsted and Son, who also designed Central Park in New York City. The garden is open to the public seven days a week and is widely known for the many varieties of magnolias as well as for examples of many other native and exotic plants.
