Henry Davis Sleeper’s home, Beauport, was named after French explorer Samuel de Champlain’s description of Gloucester Harbor. Sleeper purchased an unassuming cottage on a small lot in 1907, onto which he moved part of a Cogswell house from a site in Essex. For the next 27 years, he created his 40-room design masterpiece.

After Sleeper’s death, the McCann familiy purchased Beauport and donated it for preservation. Beauport is now a Historic New England house museum and a National Landmark, unchanged as Sleeper left it.
