Ralph Hunt completed the earliest section of what is now called the Red Mill around 1810, intending to process wool along the South Branch of the Raritan River. The wool venture failed within a decade. By 1820, Hunt acknowledged to the U.S. Census that the operation had been doing very little for several years, and he eventually lost more than 400 acres and the mills on both sides of the river.
The building did not stay idle for long. Successive owners adapted the structure for grist milling, then flour, then graphite, and finally talc production into the early twentieth century. Industrial milling at the site ended in 1928. The mill stood largely unused for three decades.
In 1960, a group of five concerned citizens, later called the Red Mill Five, purchased the property to halt its deterioration. They opened it as a small local history museum. The institution was renamed the Hunterdon Historical Museum in 1996 and rebranded as the Red Mill Museum Village in 2002.
The museum complex now occupies 10 acres along the Raritan and includes the mill itself, an adjacent limestone quarry with surviving office, stone crusher, and sorter, a one-room schoolhouse, a log cabin, and a working blacksmith shop. The property also operates the Haunted Red Mill Halloween attraction each autumn, a tradition running for more than three decades and the museum's largest annual fundraiser.
Sources
Folklore around the Red Mill centers on a young girl said to have been injured at the mill in the nineteenth century. Visitors have reported the sound of a large bell ringing without obvious source and, more idiosyncratically, the rapid clatter of an old typewriter in a room where no typewriter is on display.
The most cited account, published by Weird NJ, describes a black mass shaped like a headless torso in a woman's dress that appeared mid-air in one of the upper rooms, drifted across the space, and dissipated. Staff have logged footsteps on the upper floors when no one was upstairs, doors opening on their own, and the impression of being watched from the second-story windows by witnesses standing on the riverbank below.
The building's industrial history compounds the atmosphere. Open hoppers, narrow stairs, and grindstones still in place mean that even ordinary daytime visits include the small mechanical sounds of an old mill at rest. Seasonal investigators visiting after the Halloween event closes have recorded responses they describe as residual rather than interactive.
The Red Mill leans into the reputation each October through the Haunted Red Mill attraction, a curated theatrical event with actors, mazes, and scare effects that draws thousands of visitors and is structurally distinct from the year-round historical programming.

Media Appearances
Tour the four-story 1810 mill, schoolhouse, log cabin, blacksmith shop, and limestone quarry on the 10-acre Raritan River site. Interpretive exhibits trace the building's run as wool, grist, flour, graphite, and talc mill across more than a century of New Jersey industrial history.
A 45-minute walk-through Halloween attraction operated as the museum's largest fundraiser since 1991. Guests pass through actor-staffed scare scenes, mazes, a vortex tunnel, and the Terror Trail wrapping the mill grounds.
