A footstone is a marker at the foot of a grave. The footstone lies opposite the headstone, which is usually the primary grave marker. As indicated, these markers are usually stone, though modern footstones are often made of concrete, or some metal (usually bronze) in the form of a cast plate, which may or may not be set in concrete. The footstone may simply mark the foot of a grave, serving as a boundary marker for the grave plot, but more often provide additional information about the interred decedent. A footstone usually contains the initials of the person whose grave it marks.
