Located on the site of Abilene’s first permanent public school, built in 1890, the high school was part of an aggressive building campaign by superintendent Roland D. Green to accommodate Abilene’s rapid growth in the 1920s. The school district engaged Castle to design most of the schools built between 1920 and 1935; a few commissions went to Nichol and Campbell. Initially T-shaped, the three-story school clad in buff brick has light gray limestone Tudor details, which include shields, four-pointed arches, and delicate segmental lintels. In 1927, the east-side wing parallel to Peach Street was extended, and an auditorium was added to the back of the building. South of the school and facing Peach Street, the gymnasium (1929), with a bowstring truss roof and a two-story frontispiece, matches the simplified Tudor style of the original building. The central stepped parapet of the gym carries the school mascot, an eagle rampant above a nest.
