In a previous paper! we have given details ofan accurate survey of the monument at Stonehenge and shown how the sarsen circle and the trilithons were set out. We also discussed the possibility that Stonehenge was the central point of a solar and lunar observatory. On a subsequent visit we examined in detail (as far as crops permitted) some of the postulated sight lines. We were using the same equipment as before, namely a Longines electronic watch, a Tavistock theodolite and other surveying…

Further Work on the Brogar Lunar Observatory
In a previous issue of this journal we showed! that the Megalithic site at Brogar almost certainly contains the remains of an important lunar observatory. We gave particulars of the probable
Astronomically-oriented markings on Stonehenge
In view of the years of careful study that have been devoted to Stonehenge it may seem unlikely that any more information could be extracted from the monument, or at least from that part of it above
The Two Megalithic Lunar Observatories at Carnac
