Beauport, the 1907–1934 summer home of the collector and interior designer Henry Davis Sleeper, is a fantasy house built on the rocks overlooking Gloucester Harbor. Crowned by towers, dormers, and dovecotes, the structure encloses a labyrinth of rooms decorated to evoke different historical and literary themes. Every nook and alcove holds a composition of curiosities, folk art, china, or colored glass. The settings—playful variations on subjects like the early American kitchen, an English cottage, or the sea captain's retreat—are arranged to amuse and to stimulate the imagination.

European settlement near the Pamlico River in the 1690s led to the founding of Bath, North Carolina's first town, in 1705. By 1708, Bath had 50 people and 12 houses. It soon became North Carolina's first port. Political rivalries, Indian wars, and piracy marked its early years, but in 1746 Bath was considered for the colony's capital. However, when county government moved away in the late 1700s, Bath lost most of its importance and trade. Its original town limits encompass a historic district today. Restoration efforts in Bath have saved the St. Thomas Church, the Palmer-Marsh House, Van Der Veer House (circa 1790), and the Bonner House (circa 1830).
