The small New Castle lighthouse is one of two along the Piscataqua River as it links Portsmouth Harbor to the Atlantic.
This fortification guarding the mouth of the Piscataqua River in New Castle, New Hampshire, has a unique place in American history. It was raided twice by Patriots in 1774, and the gunpowder and cannons captured from the British were later deployed at the Battle of Bunker Hill in Boston. Its small lighthouse is one of two along Portsmouth Harbor.
The panorama view shows the lighthouse in context with fortifications originally built before 1632 and renamed Fort William and Mary around 1692.
