Ouaisne Bay is in the same bay as St. Brelade’s Bay only a small mount of rocks separate Ouaisne and St. Brelade’ Bay. There is a Martello Tower which was built for defence when England and France were at war. The tower is a navigation mark these days. The sea wall was built by slave labour by the Nazis. Behind the sea wall is a common which is the habitat of the Agile Frog which is only found in Jersey. To the right of the bay there are cliffs which there is a huge cave which prehistoric tools etc have been found. In the early 70′s Prince Charles helped to dig in the cave, they have enough material to study for at least the next  25 years, it is the best site in Europe. The beach is very safe for swimming and it is one of the beaches that gets drift wood on it. On the right hand end of the beach there is a very good example of a Nazis gun encasement for defending the beach from invasion if it had happened.
