For many years we have spent part of our summers on the island of Noirmoutier, in the French Atlantic just below Nantes. There are a two ways to get to Noirmoutier, one is by boat and the other by vehicle. And by vehicle you can take a bridge that was built in the 1970s or you can take Le Gois, a 4.5 km. French national highway built in the 1800s that runs from the mainland to the island, and which is only passable at low tide. There are some, however, who try to take the road when it isn’t low tide, or those who have been out on the flats browsing around, who get caught when the tide rises. For them towers were constructed with ladders so they can escape the incoming tide. Unfortunately there is no room on these towers for their vehicles so on a high tide it will get washed away.
