The longest day (Summer sun)

The   longest day of the year is 21 June or 22 June . It is the day when the sun is at its most northerly point and this is why "the longest day".

In Wiltshire, there is a circle of huge stones at a place called Stonehengen, and hundreds of people go there to watch the sun rise on 21 June. These stones have stood in Wiltshire for thousands of years and no one know how they got there.
