In the late 19th century and early 20th century, Wernersville was a noted resort community. City dwellers (especially from Philadelphia and New York City) traveled out to Wernersville (a stop on the Reading Railroad) to rest and partake of the cool mountain air of South Mountain. A number of large resort hotels were erected for this purpose including Galen Hall, Bynden Wood, Grand View and the Highland Hotel. Some were advertised as sanatoriums, specializing in rest cures for illnesses such as tuberculosis. The most famous of these was Dr. Robert Walter's Mountain Park (aka Walters Park). Most of these resort hotels have since been transformed into buildings for institutional purposes. Some were destroyed by fire.
