An aerial view shows the Mont Saint-Michel off France’s Normandy coast March 20, 2015. The Mont Saint-Michel 11th century abbey is expected to be entirely surrounded by the English Channel following exceptionally high spring tides. Parts of the French coast were on alert for the so-called “tide of the century”, with tidal coefficients of 118 and 119 respectively on March 20 and 21. REUTERS/Pascal Rossignol
