An Iron Age Fort...butterflies and wild flowers

I met with other members of the North Norfolk Photographic Society today at Warham Camp, an Iron Age hill fort not far from Well-Next-the -Sea.
It was a gloomy day but as rain was forecast and it actually stayed dry until we left, we can't complain.  
Such a pretty spot and as it's chalk soil, there are lots of lovely wildflowers to photograph when the butterflies are misbehaving and not posing for the camera. The main photo is of a Chalkhill Blue, also see extra of harebells.
