A bit nippy?

       SO - I kept me Jersey on.        ;¬)     
Alice and I were in Jersey YONKS ago; she might have remembered BUT damdifIcan!
       There's a LOT of Jersey we didn't see in the few days we were there, this being one of them; which we/I was unaware of - until tonight.  
       Online look about it appears to be:-
"FALDOUET DOLMEN
This Dolmen can be found just off a small country lane overlooking the east coast above Gorey.  It dates back 6000 years (about 2000 years before Stonehenge and the Pyramids!).  In its excavated form, you can wonder how Jersey’s first residents, who had adopted agriculture rather than being hunter-gatherers, moved stones weighing 25 tonnes up to this high spot from the beaches.  It aligns with the rising sun on the equinoxes, reinforcing the sun’s importance and growing season to these farming people."
