Maple Hill Cemetery is the oldest and largest cemetery in Huntsville, Alabama. Founded on two acres in about the year 1822, it now encompasses nearly 100 acres and contains over 80,000 burials. It was added to the Alabama Historical Commission's Historic Cemetery Register in 2008, and to the National Register of Historic Places in 2012. Its occupants include 5 governors of Alabama, 5 US senators, and numerous other figures of local, state, and national note. It is located east of the Twickenham Historic District.
The Huntsville Meridian intersects Maple Hill Cemetery. Plotted in 1807 by surveyor Thomas Freeman, it is the longitudinal line from which all land in North Alabama was surveyed. The tallest monument in the cemetery was erected on the meridian by another surveyor, Richard W. Anderson, "in memory of deceased relatives and to perpetuate the Huntsville Meridian."
