There are many more stone circle in the UK - not only Stonehenge.
In Cornwall located is the "Merry Maiden stone circle"
The name of the Merry Maidens refers to the legend that the stones were nineteen maidens from a wedding party who were dancing in the field one Sabbath eve by music from two pipers. As the night turned into the Sunday they continued dancing to the wild music and were turned to stone for their impiousness. The Pipers were similary petrified, and they now stand as two standing stones in a nearby field.
Age about 2500-1500 BC
