Roseland Cottage, also known as Henry C. Bowen House or as Bowen Cottage, is a historic house located on Route 169 in Woodstock, Connecticut. The house was added to the National Register of Historic Places in 1977, and was declared a National Historic Landmark in 1992.
It is now owned by Historic New England, a non-profit organization that preserves the historical value of the house and operates it as a museum. It is open several days a week from June 1 through October 15.
Roseland Cottage was built in 1846 in the Gothic Revival style as the summer home of Henry Chandler Bowen and family. The entire complex, with a boxwood parterre garden, an icehouse, garden house, and a carriage barn with a private bowling alley, reflects the principles of writer and designer Andrew Jackson Downing. In his widely popular books, Downing stressed practicality along with the picturesque, and offered detailed instructions on room function, sanitation, and landscaping.
