Beauport, Sleeper-McCann House, was the summer home of one of America’s first professional interior designers, Henry Davis Sleeper. Perched on a rock ledge overlooking Gloucester Harbor, Beauport became Sleeper’s retreat, backdrop for entertaining, professional showcase, and an inspiration to all who visited. After Sleeper’s death, Beauport was purchased by Mr. and Mrs. Charles McCann, who left most of Sleeper’s arrangements and collections intact.
