Lancaster’s most important homegrown architect, C. Emlen Urban, designed this school in 1899. The Lancaster school board accepted his design rather than designs submitted by Lancaster architects D. M. Rothenberger and Frank J. Otter.
The building has ornate classical details, including a dentilled-and-modillioned pediment over the central bay, an oculus window, and an intricate wooden cornice. Above the pedimented entry two paired windows are surmounted by a fanlight and a festoon of carved fruit. Brick pilasters have classical capitals.
