Schule am Meer, Engl. School by the Sea, Hebrew בית ספר ליד הים, also known as S.a.M. or SaM, was a private, holistically oriented coed progressive boarding school on the East Frisian island of Juist in the Free State of Prussia of German Reich, located between Wadden Sea and North Sea. It was the only German school that built its own free-standing theatre hall in 1930/31, right during Great Depression, which was also intended to train amateur play teachers throughout German Reich. This and the remaining other large building Arche (= Arch) of the former school today are due to demolition.
