It is also described as a neighborhood focal point and the most elaborate of the schools designed by its architect, Charles M. Bartberger.","narrative":"Built in 1899 on Friendship Avenue in Pittsburgh's Friendship neighborhood, this two-story brick and terra cotta school was designed by Charles Mathias Bartberger in the Beaux Arts style. Its central pavilion is dominated by a projecting pedimented portico with four fluted Composite columns, and the pediment carries an allegorical carving of two horses, an eagle and a ship. The cornice mixes seven different moldings, and anthemion antefixes decorate the roof corners. Inside, a tiled central hall with oak wainscoting leads to fifteen original classrooms. The school was originally part of the Liberty School District and was later known as Friendship Elementary School. Its ornate design is regarded as unusually lavish for an elementary school, and it became a focal point for the neighborhood. A multi-purpose room added in 1961 was designed by Frances W. Swem to address the school's lack of a public assembly space.","period_of_significance":"1881-1900","architect_builder":"Charles M.
