About Franklin

Set in the scenic Wallkill River valley of Sussex County, Franklin is a quiet small town of about 5,000 residents with a fascinating claim to fame. Known as the "Fluorescent Mineral Capital of the World," the borough grew around rich zinc mines that once drew workers from across the globe. Today, that history lives on at the Franklin Mineral Museum, where visitors can see world-famous glowing rocks and learn about the local geology. Modern Franklin maintains a relaxed, down-to-earth atmosphere, with quiet residential neighborhoods branching out from Main Street.
