Alley No. 3-R's angular arrangement of tombs gives it a feeling different from alleys located near the edges of the cemetery. It is unclear why the tombs on the southern side of the alley slant in, though the effect is perspectival, leading toward a mature palm tree along St. Louis Alley in the background. These irregular spaces are fairly common in the center of the cemetery, where the spatial ordering caused by the presence of the perimeter walls is less evident. These interior spaces have more commonly been left unpaved as well, supporting grass and other groundcover.

The orientation map shows clusters of tombs that appear to be parallel to the original palisades of the early city fortifications.
