Among the most accepted of these conjectures is that the stone monument was meant to be a temple, a burial ground, and, seemingly the most apparent of these, a solar/lunar observatory. The main entrance of Stonehenge that has the Avenue’s opening, towards which the entire stone monument is situated, points directly at the sunrise on the summer solstice. When standing in the center of the monument, on the longest day of the year, one can see the sun rise directly over the heel stone. This seems to force a viewer to notice the sunrise on the longest day of the year. The original four “station stones” placed around the circle make many alignments to point to rise and set points of the sun and moon on winter and summer solstices. Noteworthy is that the combination of sun and moon solstice rise and set points could only be collectively arranged in a perfect rectangle at the latitude at which Stonehenge is situated. A few miles north or south and the combination would have to be a parallelogram. In addition to the station stone alignments, each trilithon in the center horseshoe corresponds to certain alignments, as there are two sunset trilithons, a sunrise trilithon, and two for lunar alignments. Not only does this show that the builders and planners of Stonehenge had a great regard for the heavens, but also that they had great knowledge of geometry and science to be able to find exact angle measurements and proportions. It can also be seen that the Aubrey Holes could be used as a system of predicting eclipses. The 56 Aubrey Holes correspond to 3 cycles of the moon’s orbital wobble (The moon’s orbit wobbles in cycles of 18.66 years) and these could be used to line up with various solar alignments in Stonehenge to predict when the sun and moon would be at the same point in the sky. By a system of moving three markers around the 56 positions of the Aubrey holes, when all three were in the same spot, an eclipse was...
