Benton Hall and Annex Building History


Upon its construction in 1887-1888, the building now known as Benton Hall housed the university's administrative offices, classes, labs and the president's office. In 1947, the State Board of Higher Education approved the name change to Benton Hall to honor the Benton County residents who originally raised the money for its construction. Today Benton Hall houses the College of Liberal Arts' music program. It is located at 1650 S.W. Pioneer Place.

Benton Annex was constructed in 1892, known as the Station Building. It housed the administrative offices and chemistry lab of the Agricultural Experiment Station. From about 1902 to 1972, it served a variety of purposes, including the bookstore, the student health center, and as a paleontology lab. About 1972 it was renamed Benton Annex. The Women’s Center has been located in the building since 1973. It is located at 1700 S.W. Pioneer Place.

Benton County History

Benton County was created on December 23, 1847, by an act of Oregon’s Provisional Government. The county was created out of lands originally inhabited by the Kalapuya people and used by the Klickitat people as hunting grounds. Its original boundaries extended to the California border on the south, the Pacific Ocean on the west, the Polk County line on the north, and the middle of the Willamette River on the east. It was reduced in size during the second half of the 19th century, and reached its present size in 1893 with the establishment of Lincoln County. There are seven states, including Oregon, with counties named after Benton.
