The Village of Käsmu was first mentioned in historical documents in 1453. According to a legend, the godfather of the village was a captain named Kasper, who, once having escaped a shipwreck built a chapel here. The Village of Käsmu was built just before the First World War, when wealth was being accumulated through sea trips. Käsmu became known as "the Village of Captains" all around Estonia. The Marine Museum is located in the building of cordon, built in the end of the XIX century. In the vicinity of Käsmu there is a picturesque boulder field running deep into the sea and also a small island covered by wood sometimes called the Devil's Island. If the water level isn't too high you can walk there jumping from one boulder to another.
