If you grew up in Essex County, chances are you've heard the name "Liberty Hall" mentioned in passing — maybe from a school field trip, maybe from a grandparent who took tea there once. It sits just over the Union County line, close enough to Maplewood and Irvington that it barely counts as a drive. But most people who pass anywhere near it couldn't tell you why it matters. That's a shame, because Liberty Hall isn't just an old house. It's one of the clearest windows we have into how New Jersey — and the neighborhoods we now call home — came to exist at all.

I taught American literature and history-adjacent texts for over 25 years before I became a REALTOR®, and I've always believed that understanding a place makes you love it more. So let's take a real look at Liberty Hall: who built it, who it protected, and why a house in Union Township still has something to say to the people of Bloomfield, Montclair, Nutley, and every town in between.

A Country Retreat That Became a Front Line

William Livingston built Liberty Hall in 1772. He wasn't planning for it to become a landmark — he was planning to retire. Livingston had spent years as a lawyer and writer in New York, and by his early fifties he wanted out of public life entirely. He bought a large tract of land in what's now Union Township, built a fourteen-room Georgian country house, and settled in to become, in his own words, a gentleman farmer.

That plan lasted about three years. The American Revolution had other ideas for him.

A Founding Father's First American Home

In Liberty Hall's very first year, a teenage Alexander Hamilton lived there while attending a nearby academy in preparation for college. Hamilton had just arrived in the American colonies from the Caribbean, largely unknown, and Livingston's household was one of the first places he called home. Within a few decades, Hamilton would help write the Federalist Papers and become the first Secretary of the Treasury. It's a strange thing to sit with: the man on the ten-dollar bill once passed his evenings in a farmhouse a short drive from where many of us now shop for groceries.

George Washington's Guest List

Livingston went on to become New Jersey's first elected governor, a role he held throughout the entire Revolutionary War. That made his family a target. British troops threatened the estate more than once while Livingston was away commanding militia or governing from safer ground, leaving his wife and children to manage alone. Yet Liberty Hall also became a gathering place for the era's biggest names — George and Martha Washington, the Marquis de Lafayette, and Elias Boudinot all visited. One of Livingston's daughters, Sarah, was married at Liberty Hall to a young lawyer named John Jay, who later became the first Chief Justice of the United States.

From Livingston to Kean: Two Centuries, One Family

When Livingston died in 1790, the estate passed to his niece, Susan Livingston Kean. For a brief period she renamed it "Ursino" after her second husband, but the original name eventually returned and stuck. The Kean family kept the property for more than 225 years, through the 19th century's Victorian building boom — which is where the fifty-room mansion visitors see today came from — and into the 20th century, when Mary Alice Kean became the estate's most devoted preservationist.

It was Mary Alice who pushed for Liberty Hall's National Historic Landmark status in the 1970s and who dreamed of opening the home to the public. That dream became reality in 2000, and in 2007 the museum formed a partnership with Kean University — itself named for the same family — securing the site's future for generations to come.

Why a Landmark in Union Matters to Essex County

Technically, Liberty Hall sits in Union County, not Essex. I want to be upfront about that. But real history doesn't respect modern county lines, and neither does a short car ride. If you live in Maplewood, South Orange, Irvington, or West Orange, Liberty Hall is closer than plenty of spots you'd drive to without a second thought.

Drive times are approximate and will vary with traffic. Always check a live map before heading out.

There's also a bigger point here, and it's one I come back to often with clients who are choosing between towns. Part of what makes a neighborhood valuable — beyond square footage and school ratings — is its connection to something larger than itself. Essex County isn't just close to a Revolutionary War landmark; it's woven into the same story. The roads our clients drive to open houses in Glen Ridge or Cedar Grove are near the same ground where a governor's family once waited out a war.

Frequently Asked Questions

The Short Version

None of this changes a mortgage rate or a listing price. But it's the kind of detail that makes living somewhere feel different than just residing there. When my clients ask me what makes Essex County worth putting down roots in, I don't always start with the schools or the commute. Sometimes I start with a house a few towns over, still standing after 250 years, that watched a country get built one difficult year at a time.
