Other structures of the Salisbury Plain Stonehenge, while it is for this theorizing the main target, is not the only interesting site in this area. The following are some others that could add to the possibility of an argument for Stonehenge, or, could lead to another place altogether. The possible connections with it, or, TDB will be listed in brief. N. of Stonehenge, served as some sort of ceremonial path or enclosure. N.E. of Stonehenge.
Present theory is that it, like Stonehenge, was probably a temple or public meeting hall, or both.
N. of Woodhenge, purpose unknown. This was my first target initially, and still holds the possibility of being the correct place, but that is for later, maybe. Still, I felt it was sufficient enough to present this idea briefly as a possible answer for the 2nd location question. If nothing else, maybe this will be the case in this instance.
