Gould.","why_significant":"The school is a well-preserved example of Renaissance and Colonial Revival institutional architecture and the only surviving Somerville work of architect Aaron H. Gould. It stands on the site of earlier Spring Hill buildings and reflects the growth of city facilities during rapid population increase around 1900. It was also the first H-plan school in Somerville.","narrative":"Martin W. Carr School, completed in 1898 at Atherton Street in Somerville's Spring Hill neighborhood, is a three-story red brick building with an H-shaped plan. Two classroom wings flank a central hall and grand staircase. Granite trim, rusticated first-story brick courses, round-arched third-story windows, a slate hip roof and a Palladian-motif window over the main entry give it a formal Renaissance and Colonial Revival character. Architect Aaron H. Gould designed it as a 14-room grade school with two manual training rooms, and it was the city's first H-plan school, a layout meant to bring light and air into classrooms. It replaced an 1850 primary school and an 1852 church, and it served a city whose population rose from about 40,000 to over 61,000 between 1890 and 1900. Named for jeweler and School Committee member Martin W. Carr, it is Gould's only surviving Somerville work and retains its original design and setting.","period_of_significance":"1800-1899","architect_builder":"Aaron H.
