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

Your kind donation today will ensure that you can step into your community’s past. You can engage with history where it happened. You can thrill to the sound of music within the Mansion’s breathtaking walls. And you can share unforgettable moments with others who love and appreciate history, art, and music as much as you do.

Want to share your time and talents to preserve this unique piece of your home’s history? Volunteer with Friends of Kilmer Mansion!


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…

The Rose and Kilmer Mansions

The Kilmer family has a fascinating and colorful history. They were creators of the famed Swamp Root remedy. Founders of the Binghamton Press. And owners of Kentucky Derby winner, Exterminator. 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!
