It has a non-contributing garage on the lot.","why_significant":"It is a substantially intact, representative example of cobblestone construction from the Middle Period (ca. 1835-1845) in Western New York. It is also tied to rural education in Hartland, where it served as a one-room school until 1947. The nomination calls it an extremely rare surviving cobblestone building built for education.","narrative":"Built around 1845, this one-room cobblestone schoolhouse sits at the corner of Seaman and Carmen Roads in rural Hartland, Niagara County. Its walls are made of smooth field cobblestones about three to four inches across, laid in horizontal rows with limestone quoins at the corners and plain stone lintels and sills around the openings. The gable end faces the road, and the front has a central recessed doorway. The school served farm families and operated until 1947, when a private owner converted it to a house and added a rear kitchen wing. Those changes left the cobblestone walls and the building's form largely intact. The nomination counts about 45 documented cobblestone school buildings statewide and calls this one an extremely rare intact survivor. It was listed for its architecture and its link to local education. The town now owns it, and the local historical society hopes to reopen it as a schoolhouse museum.","period_of_significance":"1845","architect_builder":null,"architectural_style":"Mid-19th Century: Greek Revival","criteria":["A","C"],"status_note":"Listed current function is vacant.
