Here’s a little prehistoric British inspiration for your own solstice celebration this June 21st.

EACH YEAR IN LATE June, Stonehenge draws a sizable crowd to the Salisbury Plain to celebrate a day that people have been taking note of for thousands of years. Whether you believe the summer solstice represents a convergence of kinetic energy or simply the longest day of the year, it was clearly important to the prehistoric inhabitants of Great Britain.

The stone circles of Stonehenge and Avebury – which are theorized to have charted major astronomical events like the solstices and equinoxes – get most of the press, but there are close to 1,000 such sites throughout the Isles. Below are some shots of both the big names and others you might not have heard of. For more info on any of them, check out the Stone Pages.
