Perched on the edge of the Piscataqua River, Portsmouth is one of New Hampshire's most elegant towns, with a historical center set with tree-lined streets and 18th-century Colonial buildings. Despite its venerable history as an early hub of America's maritime industry, the town exudes a youthful energy, with tourists and locals filling its many restaurants and cafes. Numerous museums and historic houses allow visitors a glimpse into the town's multilayered past, while its proximity to the coast brings both lobster feasts and periodic days of fog that blanket the waterfront.
