Front Cover: Mont-Saint-Michel and its Bay
Mont-Saint-Michel is a small island made of rock situated in Saint-Malo Bay off France’s
western coast. The island and the monastery looming at its top are frequented by Catholicpilgrimage, and, together with its bay, Mont-Saint-Michel was added to the UNESCO listof World Heritage Sites in 1979. According to legend, the archangel Michael appeared in708 A.D. to a local bishop and instructed him to build a church on the rocky islet. As such,the name of island, Saint Michael's Mount (Mont-Saint-Michel), derives from the angel’sname. Saint-Malo Bay is known to have one of the greatest tidal ranges in Europe, and thedifference between low tide and high tide can be as much as 15 meters. Therefore, in the pastMont-Saint-Michel would become an island floating in the sea at high tide, while at low tide,a natural bridge would appear connecting the island to the mainland and allowing people
to walk to and from (known as the tombolo phenomena). In 1877, a causeway was built
between the island and its nearby shoreline, making the island accessible even at high tide.
However, due to fear the environment would deteriorate as a result of changes in the tidal
flow, in 2014, the causeway was replaced with a bridge that allows the waters to flow freely.
