About This Home

19 E Mill Rd

Welcome to The Old Fort, an irreplaceable historic estate offering a rare chance to own a piece of New Jersey's past with modern-day flexibility. Set on 1.68 private acres in the highly sought-after German Valley Historic District of Long Valley, this circa 1774 stone residence stands as one of the area's most distinctive and storied homes. Properties of this caliber and authenticity seldom come to market. From its commanding presence and timeless stone construction to its thoughtfully expanded 19th-century design, the home delivers a level of character and permanence that cannot be recreated. Inside, the residence offers spacious, functional living while preserving its historic charm thick stone walls, original details, and a layout that blends warmth, privacy, and versatility. The property also includes a separate 2-bedroom, 1-bath dwelling, currently vacant, presenting immediate potential for rental income, guest quarters, or a private work-from-home setup. Surrounded by natural beauty yet conveniently located near major routes, this property offers a unique combination of privacy, land, and long-term value. Whether you are seeking a primary residence, weekend retreat, or a one-of-a-kind investment, The Old Fort represents a true legacy purchase. Opportunities like this are limited, and once sold, rarely become available again. TWO HOUSES ON ONE LOT, PUBLIC SEWER AND WATER BEING SOLD AS IS
