History
In 1920, it was determined that the existing city high school on Fairground Ave. was no longer acceptable. After reorganizing the school's district, the decision was made to build a new school. The contract for the building designed by architect J. W. Kennedy was awarded on June 22, 1920 at a cost of about $250,000. The construction of the "new" Hillsboro High School was begun in 1920, and the school opened in the fall of 1921.
Sitting atop a hill located at 522 East Tremont Street, the north-facing red brick building is surrounded by trees. Through the years, into at least the mid-1960s, the campus was often named as the most beautiful in Illinois.
In 1938, the gymnasium, sited to the south of the main building was commissioned with financing for the project coming in part from Works Progress Administration (WPA) funds.
The agriculture building was added in the 1950s to the east of the gym, and the library/cafeteria building opened in 1962 just southeast of the main building.
In 2024, construction began on a new building, intended to be the new highschool. At the time of this being written, the new building has not been finished, though it has been predicted that the building will be finished until summer of 2026.
