New Castle Island, located between the Piscataqua River and the Atlantic Ocean, is a historic and coastal Portsmouth neighborhood with a working harbor edge and windswept shoreline views. The neighborhood’s character concentrates around Fort Constitution Road by Fort Constitution Historic Site, where salt air, stone ramparts, and passing boats set the daily rhythm. Landmark homes lean Colonial and shingle-style, with narrow lanes and pocket gardens shaped by the island’s compact geography. Fort Constitution Historic Site and the New Castle Common frame the public landscape with open lawns and sea-facing paths. The Wentworth by the Sea anchors the island’s grand resort-era identity, while the Wentworth Marina keeps the waterfront active. A short causeway links back toward downtown, but the island reads as its own small world of seawalls, coves, and lighthouse views.
