Aficionados of house tours will want to build their schedules around a visit to this magnificent property, a National Landmark. It’s the product of a uniquely creative mind. Interior designer and antiquarian Henry Davis Sleeper accumulated vast collections of American and European decorative arts and antiques in his summer home. From 1907 to 1934, he decorated the 40-plus rooms to illustrate literary and historical themes. You’ll see magnificent arrangements of colored glassware, the “Octagon Room” (with the number 8 as a recurring theme), and the kitchen and servants’ quarters. To get there, take East Main Street south from East Gloucester; it becomes Eastern Point Road. Eastern Point Boulevard, a private road, branches off it to the right; Beauport is half a mile down the road.
