Thousands of people have gathered at Mont Saint-Michel in northern France to watch what has been billed as the high tide of the century wash around the picturesque landmark.
The exceptionally high spring tide, swollen by a so-called supermoon effect linked to the solar eclipse on Friday, was predicted to cut off the island from the mainland with a wall of water as high as a four-storey building.
But the tidal surge was not as high as the 14.15 metres expected, and a tiny sliver of causeway no more than a few metres wide resisted the surge of water pushed by the Moon’s gravitational pull on the sea.
Saturday’s tide on the long, sloping estuary of the River Couesnon could, however, go higher, although scientists said low air pressure might have lessened the phenomenon.
The bay on the coast of Normandy has some of the strongest tides in the world.
