offices. Built in 1832, the MPH Farmhouse is one of the oldest buildings in the Town of DeWitt. Merger Enrollment at military schools fell off in the late 1960s, as disenchantment grew with the Vietnam War. The Manlius School did not escape this trend, and financial difficulties again were on the school's horizon. At the same time, Pebble Hill was running out of room for the many students who were enrolled there. In 1970 the two schools merged to become Manlius Pebble Hill School. At first the newly merged school used both campuses, with the DeWitt campus used for the Lower and Middle Schools, and the Manlius campus for the Upper School. However, by 1973 it became impractical to run two campuses. The Manlius campus was shut down beginning with the 1973-74 school year and all classes were moved to the DeWitt campus; the Class of 1974 was the last whose commencement was in Knox Hall, on the Manlius campus. The Manlius campus was sold in 1979 to a private developer. Today Today Manlius Pebble Hill School has an enrollment of 314 students and counts members of both predecessor schools as well as those who attended MPH among its more than 4,600 alumni. It is accredited by the New York State Association of Independent Schools, of which MPH is a founding institutional member. In 2019, the school is ranked by Niche.com as the #1 private school in the Syracuse, New York, area. Buildings Notable people Heads of school Bishop Frederic D.
