Old Town was the original urban core of Portland. It straddles West Burnside Street and includes an area under the Burnside Bridge. The Portland Skidmore/Old Town Historic District, created in 1975 and roughly bounded by Naito Parkway, Everett Street, 3rd Avenue, and Oak Street, is an important part of Old Town Portland. Attractions include the Saturday Market; the Shanghai tunnels; and Ankeny Square, site of Portland's oldest public art work, the Skidmore Fountain (dedicated September 22, 1888). The fountain, designed by Olin L. Warner of New York, is named after pioneer druggist Stephen G. Skidmore. Naito Parkway (ex-Front Avenue) is named after the late Bill Naito, a longtime Old Town-based businessman and developer, who with his brother Sam Naito in the 1960s helped to halt the decline of the area—then known as Portland's "Skid Road"—by opening a retail store, buying and restoring old buildings in the area, and convincing others to invest in the district over the next several years. Bill Naito died in 1996.
