But rock circles are not unusual in that area.
It reminded me a lot of the Yucatan in Mexico where there are a variety of pyramids of similar architecture at various sites (from Cozumel to Palenque to Tikal in Honduras) in a region. Or the mounds in the Louisiana area (also ancient constructions.)
Given the well-documented astronomical aspects of Stonehenge it wouldn't be a shock if the layout of associated structures also had astronomical significance, but the way it's reported here is more than a little weird.
I am not that fascinated with Stonehenge anymore after seeing those photos.
10 seconds on google shows photos and pictures of stonehenge long before 1954 and reveals the monuments were restored several times including once in 1958. See http://en.wikipedia.org/wiki/Stonehenge
