Erasmus Academy (now High School) was the earliest school in Flatbush, dating to the 18th century. Excavations in 1987, 1988, 2004 and 2010 exposed the foundations and floor of a 19th century school building under the present high school quadrangle, as well as earlier artifacts. The archaeological collection is within the NYC Archaeological Repository.
