While it’s the summer solstice in the northern hemisphere today, the southern hemisphere is experiencing its winter solstice – and events will be taking place to mark it.
In Australia, the Standing Stones in Glen Innes Highlands, New South Wales – which was set up in 1992 as a monument to the Celtic heritage some people have in Australia – sees a ceremony each year for the winter solstice.
The 24 standing stones represent the 24 hours in a day and are positioned in a circle, and visitors can watch the Sun rise through the gaps in the stones.
In New Zealand, the Māori culture celebrates Matariki from 19 June to 22 June, which marks the Māori New Year and is signified by the Matariki cluster of stars reappearing in the night sky.
Over in Peru, Inti Raymi – also known as The Sun Festival – takes place on 24 June each year and was one of the most important festivals for the ancient Inca Empire.
It took place to worship the Sun god Inti and today, a symbolic sacrifice is staged using an animal, but it doesn’t come to any harm.
