Silbury Hill

I spotted a shot of Silbury Hill, near Avebury, surrounded by water on social media, so just had to take a look for myself.  

Silbury Hill is a prehistoric artificial chalk mound near Avebury in the English county of Wiltshire, and is part of the Stonehenge, Avebury and Associated Sites UNESCO World Heritage Site. It is the tallest man-made structure in Europe and was built in successive layers between c.2400–2300 BC.

Apparently, the surrounding fields flood most winters, though I've only just became aware of this.  Archaeologists are not sure whether the "moat" is deliberate, or simply the result of the chalk being dug out, but it makes for unique view, especially with the sun breaking through heavy clouds to give a Dark/Light sight.
