What you need to know ahead of solstice celebrations

Thousands are set to descend on the ancient stone circle to witness the sunrise on the longest day of the year

Thousands of people are set to mark the summer solstice, which signifies the end of spring, and for many is a spiritual celebration at dawn.

Each year, people journey to Stonehenge in Wiltshire to witness the first rays of sunlight piercing through the ancient stone archways.

The design of the monument, built about 2500 BC, means that on summer solstice the sun rises behind its 'heel stone' and its first rays shine into the heart of Stonehenge

This year the alignment will fall on 21 June at 03:42 BST.

Some come to worship, and others just want to enjoy the atmosphere

What makes the solstice the longest day of the year?

The summer solstice occurs when the earth's northern hemisphere is most tilted towards the sun, making it appear at its highest point in the sky.

Without this tilt, there would be no seasons due to an equal amount of daylight all year.

It is the time of year when the position of the rising or setting sun stands still in its movement along the horizon.

The word solstice comes from the Latin words for sun (sol) and to stand (sistere).

As the sun ascends, lots of people make wishes for the year ahead

How is the summer solstice celebrated?

Many people gather around the Stonehenge circle, which is believed to have been used as an important religious site by early Britons about 4,000 years ago.

According to English Heritage, it is likely worshippers conducted rituals and ceremonies relating to the changing seasons, the sun and the sky.

For Neolithic people, sunlight provided warmth for them and their animals and for helping crops to grow.

Druids and pagans joined a colourful mix of visitors

Today, people travel from around the world to witness this sacred alignment, and druid ceremonies are often performed with prayers, rituals and drums.

Visitors are also permitted to be closer to the stones on this special day, potentially even touching them.
