A grey old day. Baulked at the cost of the carpark - reversed quickly away from the barrier, fortunately this early in the season it was very quiet. Drove down the road a couple of KM and parked in the aire. Scootered the 3 km back to the carpark then caught the free bus across the new bridge. Sort of takes the romance away but very convenient. The land reclaimation has been stopped as the silting up of the river was going to make the island part of the mainland. Fortification since ancient times and a monastery since the 8th century. It is pictured on the Bayeux Tapestry - one of William's battles - involving quicksand foiling the bad guys.
