This shot shows the back of the church and the other side, with part of a gravestone in the left foreground. Notice the rounded section of the back wall.
Here are some gravestones behind the back of the church, including two circular stones that look like they may have previously been millstones used for grinding grain.
In another part of the church grounds is this curved columbarium, used to store urns that contain the ashes of the deceased, who are identified on each corresponding plaque.
The Old Trinity Church has its own website and is mentioned in Scenic USA.
