Pennsylvania has many tourist attractions, but some are so unique they must be seen and heard to be believed, including one in Bucks County, writes Kalena Thomhave for The Keystone.
Ringing Rocks County Park in Upper Black Eddy features a seven-acre field of large boulders that emit mysterious sounds when struck with a hammer. Different hammers and mallets produce various tones, allowing visitors to create their own music. The park also offers several trails and the county’s tallest waterfall to explore.
Two more landmarks near Bucks County offer equally awe-inspiring experiences.
Kelpius Cave at Wissahickon Valley Park in northwest Philadelphia is linked to a doomsday cult. Johannes Kelpius, a Lutheran sect leader, and his followers settled in the local forest in the late seventeenth century. In order to pray for the end of the world, Kelpius created what was known as Hermit’s Cave, which can be visited by walking along the Yellow Trail.
The Toynbee Tiles, featuring cryptic messages such as “TOYNBEE IDEA/MOVIE 2001/RESURRECT DEAD/PLANET JUPITER” appeared in dozens of major cities in the United States and South America throughout the 1980s, mostly in Philadelphia. While many were removed, some are still standing on Chestnut Street.
