The American Museum and Gardens, located near Bath in Somerset, England, is the only museum outside the United States devoted to American art and culture. It is based at Claverton Manor, a Grade I listed 19th-century Georgian estate overlooking the River Avon valley. The museum was founded in 1961 and features extensive collections of American folk art, quilts, Shaker furniture, and historical maps, along with period rooms that recreate historic American interiors from circa 1690 to 1860.
 
The museum grounds include notable gardens, such as the New American Garden designed by the Washington DC-based landscape architects Oehme, van Sweden. The gardens feature a prairie-style layout, an arboretum of American trees, and a reproduction of George Washington’s Mount Vernon garden, symbolizing the friendship between America and the UK.
