Bernardsville, New Jersey, United States
$13,750,000 | 1886 | 7 Beds | 8.5+ Baths | 32.22 Acres

Introducing Stronghold, a once-in-a-generation estate perched atop Bernardsville Mountain—where Gilded Age grandeur meets seamless modern sophistication. Originally built in 1886 for members of the Astor family and designed by legendary architect George B. Post, this architectural gem has been meticulously reimagined for 21st-century living while preserving its storied past.
Set on over 32 private acres of manicured lawns, towering trees, and specimen plantings, the stone residence features rough-hewn local stonework, Corinthian columns, wrought-iron balconies, and a magnificent central tower. Inside, ornate millwork, quarter-sawn oak paneling, original Tiffany glass, and restored light fixtures nod to the home’s opulent roots.
Smart-home integration via the Savant system manages lighting, climate, and security at your fingertips. The chef’s kitchen, with its wall of glass, flows into a soaring two-story family room and onto a complete outdoor kitchen overlooking the limestone-trimmed pool, island tanning deck, and elegant cabana with wood-burning fireplace.

The tower houses a speakeasy-style lounge with sunken bar and a breathtaking office with sweeping views—culminating in a rooftop perch believed to be the highest point on the mountain.
Also included: a separate 10-acre parcel with a restored carriage house and a former gymnasium-turned-recreational facility with full basketball court, fitness center, and locker rooms.
A legacy estate of unmatched heritage and elegance, Stronghold is a rare and remarkable offering in the Somerset Hills.
