Atsion Mansion
New Jersey’s Pine Barrens Iron Industry Estate — 1826 Greek Revival Mansion by Ironmaster Samuel Richards, Never Modernized (No Electricity or Plumbing), Wharton State Forest, Atsion Ironworks 1765, Joseph Wharton’s Cranberry Operations, Mullica River, Burlington County New Jersey
Atsion Mansion is a historic estate within Wharton State Forest, Burlington County, New Jersey. Built in 1826 as a summer residence for Samuel Richards, a prominent Philadelphia ironmaster who operated the nearby Atsion iron furnace, this Vernacular Greek Revival mansion is one of New Jersey’s most remarkable examples of early 19th-century architecture — never modernized to include electricity or indoor plumbing. The house remains essentially frozen in 1826. The site features one of NJ’s finest Vernacular Greek Revival mansions, unchanged since 1826 — no electricity, no plumbing, no modern alterations, remnants of the 1765 Atsion Ironworks along the Mullica River, connections to Joseph Wharton who used the estate for cranberry and peanut operations, seasonal guided tours through the NJDEP, and proximity to the Atsion Recreation Area for swimming, camping, and hiking.
The Atsion Ironworks
Atsion’s industrial history dates to 1765, when Charles Read established an iron forge here. The operation grew to include an iron furnace, mills, and worker housing, making Atsion one of the Pine Barrens’ most important early industrial centers. Samuel Richards expanded the operation and built the mansion in 1826 as his country estate. Remnants of the iron furnace can still be found near the Mullica River.
Joseph Wharton Era
In 1892, industrialist Joseph Wharton (founder of the Wharton School of Business) purchased the Atsion property as part of his massive Pine Barrens land holdings. Wharton used the mansion and surrounding land for cranberry and peanut packing and storage. When New Jersey acquired the Wharton Tract in the 1950s, the mansion and surrounding lands became the core of what is now Wharton State Forest — the largest single tract in the NJ State Park System.
The Unmodernized Mansion
What makes Atsion Mansion truly extraordinary is that it was never modernized. There is no electricity, no indoor plumbing, and no modern fixtures. The unfurnished rooms offer visitors a rare chance to see a pre-Civil War mansion exactly as its original architecture intended — an increasingly rare experience in the 21st century.
