Discover more about Peirce Island

Peirce Island, a 27-acre island owned by the city of Portsmouth, New Hampshire, is a treasure trove of history and natural beauty. Situated where the Piscataqua River meets the South End of Portsmouth, the island offers stunning views of salt marshes, tidal pools, rocky cliffs, and meadows. Historically, Peirce Island played a vital role in the defense of Portsmouth Harbor. In 1775, Fort Washington was constructed on the island to protect the Piscataqua River. Named after George Washington, the fort and its sister installation, Fort Sullivan, were crucial during the Revolutionary War and the War of 1812. Although the fort is now mostly ruins, historical markers dot the island, offering glimpses into its past. In the mid-1800s, Peirce Island transitioned into a shipbuilding center, contributing to the maritime industry. During World War II, it served as a recreation center for coastal artillery troops. Today, Peirce Island is a recreational haven with an outdoor swimming pool (open seasonally), walking paths, a playground on the adjacent Four Tree Island, and a boat launch. Visitors can enjoy picnics, admire the views, or launch a kayak for a paddle along the Piscataqua River. While a wastewater treatment plant occupies a portion of the island, the remaining areas are well-maintained and offer scenic trails and waterfront overlooks. The island is easily accessible via the Peirce Island Bridge, making it a convenient escape for those seeking tranquility and natural beauty.
