I had such plans for this post! and so drastically ran out of time!
but here are some photos of the 2 castles on Jersey, Channel Islands.
Elizabeth Castle is just off the coast by the main town in the island. At low tide there is a causeway and the Castle can be reached on foot

to the right of this photo the "duck" - the amphibious craft which ferries to and fro - can be seen,

though there are local stories of people and vehicles being cut off by the tide and once, while M. had a summer job driving bread van, one of his colleagues hoped to make it home quickly and was caught out, leaving all manner of baked goods bobbing about on the waves for the sea gulls delight.
Elizabeth castle was used heavily by the Germans, during their occupation of the island in the 2nd world war. Hence the chimneys and not very castle-like roofs, though the castle was first built in the sixteenth century and Sir Walter Raleigh lived there for a while.
I've not been out to the island for quite a few years, hence no closer photos. I'll try and put that right next time I go.
In the meantime there are some good pics
here and

here.
Gorey Castle wasn't modified by the Germans to the same extent and its a much more medieval-looking castle - its older, built in the fourteenth century, originally known as Mont Orgeuil.



it even has stocks (not fourteenth century!)

and the seagulls are ubiquitous - looking out for baked goods no doubt.
