Old Bend High School, Historic school building in downtown Bend, Oregon.

Old Bend High School is a two-story brick building with a high basement, set on a 3.17-acre parcel in downtown Bend. Its U-shaped footprint measures 120 by 247 feet, and the main entrance on Louisiana Avenue is framed by three round-arch openings supported by wide brick columns on a cut-stone foundation. The front facade has tall windows from end to end, and a wide stairway leads to the portico.

Bend's first schoolhouse opened in 1887 in an abandoned cabin near the Deschutes River. After a bond issue passed in 1913, the Reid School opened in 1914 with 241 students. Voters approved $209,000 in 1924 for a new high school, which opened on 7 September 1925 with 69 seniors graduating in May 1926. It became Cascade Junior High in 1957 and was converted to district offices in 1979.

The building's name survives in local use as "Old Bend High School," and a historic marker near the main entrance recalls its school heritage. Since 1979 the former classrooms have housed Bend-La Pine School District offices alongside several kindergarten classrooms, so children still attend class in the building.

The main entrance faces Louisiana Avenue, reached by concrete walkways across the front lawn; four other entrances sit on the east, west and south sides. The grounds are shaded by large Ponderosa pines, and the building is bordered by Wall Street, Louisiana Avenue and Bond Street in downtown Bend.

The building was designed by Hugh Thompson, Bend's first resident architect, who brought the Beaux-Arts style to the city. His design reflects the architectural foundations on which Bend built its public appearance.
