Staley MineView only
Discovered and opened in 1832, the Staley Mine was one of the earliest iron ore sources supplying the historic Oxford Furnace.

Barker's Mill (aka Nippes Armory)View only
Constructed in the early 19th century by David Nippes, this historic stone mill originally manufactured firearms for the War of 1812 before transitioning to woolen production under the Barker family. After a late-20th-century stint as a recording studio for the R&B group Boyz II Men, the complex was abandoned in the mid-2000s. Today, the multi-story stone and brick structures stand vacant and decaying along the banks of Mill Creek, surrounded by overgrown vegetation.

Friendship Historic RuinsOpen to visit
Deep in the Wharton State Forest of the New Jersey Pine Barrens lie the quiet remains of Friendship, a ghost town founded in 1869 at the center of a massive 3,000-acre cranberry farming operation. Once a bustling agricultural community, the village was eventually abandoned as the industry declined. Today, only crumbling stone foundations, cellar holes, and overgrown clearings remain, slowly being reclaimed by the surrounding pitch pines.
-
Rolling Hill Park RuinsOpen to visit
Tucked away in the woodlands of Rolling Hill Park are the crumbling stone skeletons of 19th-century mill worker tenements and industrial structures. These ruins, including the three-story Toddtown Tenement built around 1849, once housed the workforce for nearby cotton and paper mills along Mill Creek. Today, hikers can explore the roofless, vine-covered stone walls and historic foundations that stand as a testament to the area's early industrial history.

Scott's Mill Bridge ruinsOpen to visit
Located within the Fair Hill Natural Resources Management Area, this site preserves the remnants of a bustling 19th-century industrial hub along Big Elk Creek. The primary feature is the roofless, three-story stone shell of Scott's Grist Mill, which once ground flour and feed. Directly adjacent, the modern pedestrian bridge still rests on the original 1855 stone abutments of the historic covered bridge that washed away in 1946.
-
Ruins of Lincoln Blacksmith ShopView only
Dating back to the early 1700s, this sandstone ruin was once a blacksmith shop and iron forge operated by Abraham and Mordecai Lincoln, ancestors of President Abraham Lincoln. The one-story stone structure is a rare surviving example of 18th-century stone vernacular architecture in Monmouth County. Today, its roofless, weathered stone walls still stand near the roadside, offering a quiet glimpse into the area's colonial industrial past.
-
Burnt Mills Grist Mill RuinsOpen to visit
Located within the Burnt Mills Floodplain Preserve, these stone foundations are the remains of a post-Civil War grist mill. Purchased by the Schley family in 1928, the mill was dismantled, leaving behind its historic stone ruins along the Lamington River. Today, the site is surrounded by a scenic 11-acre riparian sanctuary famous for its vibrant spring displays of Virginia bluebells.
-
Salem County Insane AsylumView only
Constructed in 1870, the Salem County Insane Asylum is the only surviving first-generation county asylum in New Jersey. The three-story Italianate brick structure was built to relieve overcrowding in state facilities but has been vacant and decaying since county offices relocated in 1995. Today, the boarded-up building stands as a haunting roadside relic, complete with its original wooden rooftop belvedere.
