With every dollar you give, you will be rebuilding the Kilmer Mansion’s deteriorated porches, stone by stone. Restoring the collapsed floor of the north terrace. And making sure that the Mansion remains a special part of our community now and for the future.

One of the most eye-catching buildings on Binghamton’s West Side, the Kilmer Mansion… stands out with its turrets and gargoyles. The Kilmers stamped their name all across Binghamton, literally etching it in stone on buildings they owned.WICZ

Our neighborhoods have lost too many special places through neglect and demolition. As these places disappear, pieces of our history and identity are destroyed along with them.

Who can we rely on to make sure the irreplaceable Kilmer Mansion does not disappear?

In 1890 many of Binghamton’s wealthiest families lived in palatial mansions just west of the Chenango River on Riverside Drive. At that time four mansions lined the south side of the drive…Three of the mansions are long gone…

If you have had the pleasure of spending time in Kilmer Mansion, you have likely sensed the merging of past and present.

You might have felt the tranquility that comes with being surrounded by gleaming patinaed wood. And the aura of yesteryear.

Perhaps you have been filled with a sense of calm as you gazed with wonder at the embellished plaster work. Decoratively painted ceilings. And shining marble.

In this remarkable place, you might have learned the fascinating and colorful history of the Kilmer Family.

Purveyors of the world famous Swamp Root on which they built their fortune.

Founds of the illustrious Binghamton Press.

And owners of the much-beloved Kentucky Derby winner, Exterminator — who inspired an entire city with his indomitable spirit.

They even sold their private yacht Remlik (read it backwards) to the Navy to serve as an armored patrol vessel during World War I.

Jonas M. Kilmer had one child, Willis Sharpe Kilmer. They built exquisite mansions, side-by-side, at the east end of Riverside Drive.

The Willis Sharpe Kilmer Mansion was torn down decades ago.

So was its next-door neighbor, the Edward Rose Mansion.

The Robert Rose Mansion (pictured to the right and below) was demolished in 1980 despite protests.

Since 1950, Temple Concord has been steward to the Jonas M. Kilmer Mansion, saving it from the fate of its three sister mansions.

The Jonas M. Kilmer Mansion is the sole survivor of the four original mansions. It is home to one of the last grand parlors of the Parlor City.

Built in 1898, it is part home and part castle.

It features turrets and towers, ballrooms and balconies.

Visitors will find fine stonework and masterful woodwork.

The mansion is never uninhabited.

Lions roar on the exterior.

A gargoyle peeks out from beneath the eaves.

A dragon guards the entrance.

And painted angels dance across the ceiling.

You can savor the unique beauty of this historic treasure. Join us for tours, music concerts, and other special events!
