Off the north east coast of England is a wee tidal island that can only be accessed by car twice a day. Or you could probably swim across to it if you’re that way inclined. It’s a bit famous – some religious types were hanging out there minding their own business and drinking mead, until a bunch of Vikings came and destroyed the place in the late 8th century.
The Vikings killed or enslaved the monks, pinched all their nice stuff and kicked off what became known as The Viking Age of generally being a pain in the arse. The Vikings eventually nicked off and the Danes had a crack at invading the English and … wait … this is turning into a history lesson. Use Google if you’re actually interested in history.
Anyway, the devotees were able to come back, got themselves some new digs (a church AND a castle) so now it’s a place of pilgrimage and generally touristy things.
It’s a nice place to spend the day rambling around the ruins of the medieval priory and the castle and generally taking in the atmosphere.
