TIL about Saint-Malo, Brittany. This city on the French coast has some of the highest tides in Europe, rising as high as 40 feet during parts of the year, and the water withdrawing hundreds of yards. A sea wall, built in the 17th century, protects the city from the tides.

The buildings along the coast are also built as breakwaters, and multiple layers of glass are required to withstand the waves. The first expeditions to Canada sailed from Saint-Malo, and it later became a home to pirates that would harass British ships in the channel.
