Roosevelt Junior High School is a historic school located in Decatur, Illinois, United States. Built from 1917 to 1921, the school was the first exclusive middle school in the city. Decatur architectural firm Brooks, Bramhall & Dague designed the school in the Collegiate Gothic style, a popular choice for educational buildings at the time. The three-story building is built from red brick and features terracotta trim designed to resemble stone. The front entrance is designed to resemble a castle's keep, with octagonal turrets on either side and the extensive use of terracotta to form arches, piers and spandrels. The rest of the building features buttresses and Gothic arches throughout, and a battlement surrounds the edge of the roof. The school operated continuously from its opening until 2000. In recent years, the building has been converted to an apartment complex.
