The building was later used as a military academy and then as a public high school.","why_significant":"The nomination argues the building is an excellent example of the Tuscan Villa Italianate form, which it describes as rare in Washington County. It is also associated with the Trinity Military Academy and with a visit by General Grant, whose visits are recorded in a marble fireplace inscription.","narrative":"Built in 1857 as a private residence in Washington, Pennsylvania, this large red brick house is a Tuscan Villa in the Italianate style. Its wings are low-pitched and decorated with dentils and coupled brackets, and the tall segmental arch windows have matching hood molds. A loggia of Tuscan columns with stilted arches runs along three sides of one wing, and a square wood cupola rises above the center gable, echoing an Italian Renaissance campanile. Joseph McKnight occupied the house until 1879, when William W. Smith, a Washington merchant and banker, bought it and funded its conversion into the Trinity Military Academy under Trinity Episcopal Church. A two-story addition by McKim, Mead and White was built at the rear in the late 1870s. The property was bought in 1925 by four surrounding townships and reopened as a public high school. A marble fireplace in one office records three visits by General Grant. The building is valued because the Italianate villa form is rare in Washington County.","period_of_significance":"1857","architect_builder":"McKim, Mead and White (architects of the rear addition); T.V.
