Montgomery Park is an office building and former Montgomery Ward mail-order catalog warehouse and department store located in Portland, Oregon, United States, built in 1920. It is listed on the National Register of Historic Places under its historic name Montgomery Ward & Company Building. The building is located on property once used for the Lewis and Clark Centennial Exposition, of 1905. It was occupied by Montgomery Ward from 1920 until 1985, although the majority of the company's operations at this location ended in 1982. The building is the second-largest office building in Portland with . Description and original uses At the time of its completion, in September 1920, the building was the largest in the city, as measured by floor space, which was approximately originally. A wing was added to the building's northwest corner in 1935–36, changing what had been an L-shaped building to a roughly U-shaped one. The building has nine floors plus a basement. The 4th through 9th floors were used almost exclusively as warehouse space, while most portions of the 2nd and 3rd floors functioned as office and mail-order workspace. The first floor was used primarily for loading and unloading of freight arriving and leaving by truck or rail and temporary storage of such goods. Three rail spurs served the facility, extending into the ground floor. Among other things, the building is known for its large steel-framed roof sign, the largest sign in Portland, which was constructed in 1925. Retail store Retail service at this location was relatively limited in its first years. A 1936 expansion added retail space, covering a variety of goods, occupying a new mezzanine floor and parts of the 2nd and 3rd floors. A tire store was opened in an adjacent annex. In the post-World War II years, the Vaughn Street store's business declined steadily. An increasing proportion of the store's customers were attracted to new suburban shopping malls, and in the early 1970s Montgomery Ward began to follow the same path itself, opening stores at Mall 205 and Jantzen Beach Mall, along with a stand-alone store in Beaverton. The Northwest Portland store closed in July 1976, and the building remained in use only for warehouse and mail-order functions and as a "catalog overstock outlet". In 1978, the company built a new warehouse in Portland's Rivergate Industrial District, and in 1982 it closed the Northwest Portland warehouse, eliminating 500 jobs at the site.
