Seaside Heights tells the history of a timeless seashore resort community located on a barrier island nestled between the Atlantic Ocean and Barnegat Bay. The 224-acre town was settled by residents of Philadelphia and Camden, who purchased white-sand lots to escape city life for the brisk ocean breezes and tranquility that Seaside Heights offered prior to World War II. Seaside Heights uses the scenes captured in vintage postcards, some of them very rare, as a study of the changes that have occurred in the town since its incorporation in 1913.
