Image of Brainport Bay Solar Alignment by greywether

The alignment viewed over the sighting stones on the main sighting platform {C}.

Not taken from the viewing area but taken to show the approximate place on the horizon where the midsummer sunrise takes place. Due to the cloudy conditions, the far distant hills are not fully visible.

Although the apparatus for an accurate sighting appears to be in place, one problem is that the declination here would not indicate the solstice in (say) 1800 bce but around 15 days before or after.
