A solstice happens when the Sun in the sky is at its furthest point from the celestial equator.
On the June solstice it reaches its northernmost point, and the Earth’s North Pole tilts towards the sun, at about 23.5 degrees.
Apart from the well-known links between the solstice and ancient stone structures, another extraordinary ancient object has connections to this celestial phenomenon.
The Nebra Sky Disc is a 3,600-year-old bronze disc which, according to UNESCO, features "the oldest concrete depiction of cosmic phenomena worldwide."
The disc is such an extraordinary piece that it was initially believed to be a forgery.
