The early 19th-century village contains a working mill with gristmills and sawmills, a general store, a blacksmith shop and restored houses.

Rutherfurd-Stuyvesant Estate
The Rutherfurd-Stuyvesant Estate dates back to the 1700s and featured a large mansion and many outbuildings. By the mid 20th century, the mansion had burned down and the remaining buildings were in very poor condition. In the 1960s, the estate was purchased by the State to build route 80, which divided sections of the estate with an eight-lane highway. In the 1970s, the Allamuchy Mountain land became part of Allamuchy Mountain State Park. Tranquillity Farms, on the other side of the highway, remains a privately operated commercial farm.

Locally, the ruins of the Rutherfurd-Stuyvesant Estate have become known as "Profanity House" because many of the buildings and ruins have been vandalized and covered in explicit and graphic graffiti. In recent years, the estate has suffered from arson damage.
