The land on which stands the enormous Beauport Sleeper-McCann house was bought by Henry Davis Sleeper in 1907. He had the house built over the following year, and it is now a National Historic Landmark. The mansion and gardens overlook Gloucester Harbor on Eastern Point, a gated community. Henry Sleeper (1878-1934), a famous interior designer, made the mansion his summer residence. To say the house is bizarre is an understatement. Sleeper decorated each of the 40 rooms with a different theme--Early American, French, Medieval, Chinese--displaying furniture, artwork, curiosities and antiques he picked up on his travels. His "Franklin Game Room" honors the Founding Fathers, with their portraits and miniature likenesses. The labyrinthine layout is impossible to navigate without an experienced guide. Each room is more astonishingly decorated than the next. One room was built around a set of wooden curtains. The "Master Mariner's Room," overlooking the harbor, was built to resemble a ship's bow, complete with nautical appointments. Each room has a descriptive name, such as the Red Indian Room, the Golden Step Room and the Octagon Room, which indeed has 8 sides. Sleeper's offices were on State Street and Boylston Street during the 1920s. His clients included Isabella Stewart Gardner and Hollywood actors. This house has to be seen to be believed. It's like stepping into another world.
