It was built in 1923-1924 as an elementary school in the Colonial Revival style.","why_significant":"The nomination argues the school is significant for its role in the School District of Philadelphia's building program of the early 1920s, when many schools were authorized. It is one of eight elementary schools built from the same set of plans, School Board Type Number 137, and is regarded as a model for demonstration schools. The building is listed as part of the Philadelphia Public Schools Thematic District despite later window replacement.","narrative":"At the southwest corner of 17th and Lindley Streets in Philadelphia stands a three-story brick elementary school built in 1923-1924 on a raised brick basement. Designed by Irwin T. Catharine and built by Sinclair & Grigg, it is one of eight schools erected from School Board Type Number 137, a standard plan that followed design principles set out by H. deCourcy Richards when he was Chief Designer for the district. The building has a nine-bay front with recessed outer bays, stone arched surrounds on the first level, a double stone cornice, and a brick parapet with the school's name carved into it. Its side elevations have a projecting entrance pavilion framed by double pilasters and a large arched opening. The school was part of an ambitious building program in which the district authorized eight junior high schools and thirteen elementary schools between 1921 and 1923. It is regarded as a model for demonstration schools in the city and the nation. Its windows were replaced around 1986, which the nomination weighed against its overall integrity.","period_of_significance":"1923-1924","architect_builder":"Irwin T.
