History of the Mansion

The 6,750 square foot Victorian mansion was built in 1820 by the wealthy Joseph Andress, who spared no expense in its creation. Having no family of his own, Joseph's siblings and their families lived here with him. One of his siblings, Jacob, lived in the mansion and his wife Minerva and their son, Gilbert, who was sickly from birth. A rope-pull dumbwaiter was installed in the mansion, making it easy to move the wheelchair-bound Gilbert throughout the floors. Gilbert died just 3 days shy of his 9th birthday. He is buried a quarter mile up the road from the mansion, his grave adorned with a tall monument that bears a bronze cast of his likeness. His parents are interred there as well. On the grounds there once stood servant's quarters, a luxury of the times, but the structures succumbed to a fire in the 20th Century. Over the years, the mansion changed hands and began to fall into disarray. During the 1970's, the building was converted to a rock club, which by all accounts, drew an unsavory element into the neighborhood. After the club was shut down, the house took a sharp decline and was left to vandals and vagrants. In 1983, the mansion was partially restored and used as a restaurant, an antique shop and then abandoned again. A throwback to an era when enterprising railroad operators built their tracks in the direction of their real estate holdings, the three-story Hainesburg Mansion House-known to locals as the Hainesburg Inn-dominates the village with its gold topped cupolas. The Mansion House was among the proliferation of elegant homes and hotels that sprung up in the area of the Delaware River as trains brought passengers from New York City to beautiful rural, largely undiscovered swaths of western New Jersey.
