Almost all the walls and fences that used to surround family plots in Allegheny Cemetery have been taken down, but there is an important exception to the rule. In one section of the cemetery are several circular plots where the low stone walls are maintained. Most of them have a central monument with individual graves orbiting it around the edge of the circle; one or two have no central monuments.

The Head plot (above) and the Fitzsimons-Morrison plot (below) are two good examples of the style.
