Stevens Estate at Osgood Hill
In late September, I took a daytrip to Andover, MA. After a relaxing morning at Addison Gallery of American Art , I took a walk at Osgood Hill, a North Andover trail and a partner of Mass Audubon . While there, I saw Stevens Estate , a 1886 building on 143 acres listed on the National Register of Historic Places since 1999 .
