"The observatory defines the four main positions of the Moon and three main positions of the Sun during a year, the autumnal and vernal equinox and winter and summer solstice." One specially positioned marker shows that the observatory was also used to follow the movement of the star cluster Pleiades.
Jedan od posebno pozicioniranih markera pokazuje kako je opservatorij također korišten za praćenje kretanja sazviježđa Pleiades.
