LANESBOROUGH — How much does it cost to own a piece of American history? In Lanesborough, the answer is $1.985 million.

That's the asking price for one of Berkshire County's most historic homes, Constitution Hill Farm at 10 Goodell Road, which is now on the market.

The home was built in 1750, and got its name in 1788 when Jonathan Smith lit a bonfire on the then unnamed hill to celebrate Massachusetts' ratification of the Constitution, making it the sixth state in the burgeoning nation.

"Don't get me wrong, there's a lot of historical places in the center of Boston," said Steve Ray, the agent showing the home. "But, when you combine it with the land ... there's not a lot of places you could go and find this."

Constitutional Hill Farm has 200 acres of land, including a potential spot where Jonathan Smith lit a bonfire to signify Massachusetts' ratification of the constitution. Steve Ray, the agent showing the home, pointed to part of Constitution Hill.

The original farmhouse predates the Declaration of Independence by 26 years. In addition to Smith's bonfire, the hill was also the birthplace of Henry Wheeler Shaw in 1818. Shaw was a humorist who wrote under the pen name Josh Billings.

The farm estate sits on just under 200 acres, and it has a main home, dairy barns and equipment that still have good structure, a hay barn actively used and several more, less established structures related to farming.

It's considered one of the oldest continuously operated farms in Berkshire County, said Ray, who is the president of 413 Real Estate.

For part of its life, Constitutional Hill Farm operated as a dairy farm, with two dairy barns erected in the 1900s. These pumps would have removed and transported milk.

In the primary home itself, much of the wood — including support beams, flooring and doors — have been preserved since the original construction, Ray said. The previous owners "preserved them as opposed to filling them in."

Additions to the house include an in-law suite with a full kitchen and bathroom above the garage. The main residence has three additional bedrooms, two bathrooms and one half-bathroom.

One of the additions to the 1750 home is an in-law suite that includes a full kitchen and bathroom.

The front half of the property — the side on Goodell Road — has a stone wall that Ray said is likely as old as the home itself.

The current owners, who were actively farming the land as well, are selling the property after enrolling their child in a school in Newtown, Ray said. They bought the home for $950,000.

Although there have been additions to the home, most of the wood — including the support beams seen in the attic — is original, dating back to 1750.

Abutting the property are trails owned and operated by Berkshire Natural Resource Council that climb Constitution Hill. That preservation helps solidify the farm's historic feeling. Standing near the back of the farm, with freshly cut hay drying in the sun, it's easy to imagine the American Revolution. Even power lines and modern farming equipment don't break the illusion.

"It's a shame sometimes to see them go," Ray said, referring to the current owners. "It's always nice to see it go to somebody who's going to be a steward of the land and the property to make sure we're around for another hundred years."
