The couple bought the nearly 200-year-old property in 2008 for $1.05 million. Since then, they've spent years restoring the 1811 home and expanding it to incorporate its rich history and modern conveniences, according to Mansion Global.

The 103-acre estate is surrounded by lush, rolling fields with picturesque views of the Berkshires in the distance.

According to the listing, the six-bedroom holiday home embodies the best of three centuries: early 19th-century Federal architecture, 1920s country estate style, and 21st-century structures and systems."

According to Mansion Global, the farmhouse "was once the home of U.S. Ambassador William C. Bullitt, who served under President Franklin D. Roosevelt."

Traces of history can still be found in the 10,747-square-foot home. There are 11 fireplaces, custom woodwork, lots of built-ins (in the wood-panelled library and elsewhere), wide-plank floors and exposed-beam ceilings. There's even a Dutch door leading to the private backyard.

The nearby kitchen features custom cabinetry and a spacious island with a sink.

The two-story great room features a fireplace, dark wood exposed beams, cathedral ceilings and floor-to-ceiling library-style bookcases with ladders. According to Boston.com, the space is used as a recording studio for the "You Are The Best Thing" singer and is where Lamontagne recorded his fourth album, "God Willin' & the Creek Don't Rise."

Speaking of the best views of the surrounding natural beauty, there is a covered front porch and a pond that is flanked by stunning mountain views.

The private estate is surrounded by 438 acres of protected land, as well as a 19th-century, three-story barn, a stone cottage with a fireplace, a newer two-story carriage house and a garage.

La Montagne will begin touring in September with performances in Atlanta, Boston and Brooklyn.
