The point at which the Earth's poles are at their most extreme inclination relative
to the Sun. This occurs twice a year: the Summer Solstice gives us the longest
day of the year, while the Winter Solstice gives us the shortest.
Sunrise on the Summer Solstice of 2049 BCE, as seen from the eastern coast of England: an
unusual event in which Venus and the Sun rose almost simultaneously. The wooden Bronze Age
monument known as 'Sea Henge', which was aligned with the solstices, was completed just prior to
this event, and is possibly connected with it.
