Sna Broch, Fetlar, Shetland Isles, Scotland.
All that remains of this broch site are its large defensive earthworks. The actual broch was lost to coastal erosion before modern times. The banks are partially faced in stone, the ditch is deep and waterlogged - likely to contain organic remains.
Sna Broch continues to loose its fight with the sea, I found a stone fishing/loom weight on the beach at the site of a recent colapse. (see annotation 3).
The site was photographed using kite aerial photography, vertical photos taken at c.40 metres and low level oblique photos at 4 - 8 metres.
