On a narrow point of land at the southeast corner of New Castle Island, where the Piscataqua River empties past Little Harbor into the open Atlantic, sits one of New Hampshire’s most quietly rewarding historic sites. Fort Stark spent more than two centuries as a working military installation, a place built to fire on ships and defend the mouth of the harbor. Today the guns are gone, the concrete bunkers are weathered and graffiti-marked, and the loudest thing on the peninsula is usually the wind. As the country marks its 250th birthday, the old fort offers a rare combination in a busy summer state: real American history and a spectacular ocean view, with almost no crowd, as New Hampshire Public Radio’s Rick Ganley reported in the outlet’s NH at 250 series.

The land was historically called Jerry’s Point, and the military found it valuable for the same reason day-trippers love it now. From this spit of rock you can see the water in nearly every direction, which made it an ideal spot to watch for and fire on any hostile vessel trying to reach Portsmouth Harbor. What began as a colonial-era gun position eventually grew into a sprawling coastal defense complex, then faded into the peaceful state historic site that greets visitors today.

Two centuries of guarding the harbor

The fortification story here is long even by New England standards. The point was first fortified in 1746 as Battery Cumberland, armed with nine 32-pounder cannons, heavy guns for their day. Decades later, in 1794, a new nine-gun battery went up on the site as part of the young nation’s First System of coastal fortifications, the federal government’s earliest coordinated effort to defend the American shoreline after independence.

The site stayed in service through the country’s early conflicts. During the War of 1812, a company of roughly 120 militiamen under Captain William Marshall garrisoned the works, standing watch over the harbor entrance during a war that saw the British navy active up and down the Atlantic coast. Each generation that felt threatened from the sea reinforced this same strip of New Castle rock, layering new defenses on top of old ones.

The most substantial construction came at the turn of the twentieth century. Work on a modern fort began in 1901 and was completed in 1905, producing four gun batteries of reinforced concrete. Between 1907 and 1909, the Army added facilities for controlling an underwater minefield in the harbor, a system that would let defenders detonate charges beneath enemy ships trying to slip past. Those low, blocky emplacements are the structures visitors clamber around today, and their scale hints at how seriously the military once took the defense of this coastline.

A gun so loud it broke the Wentworth’s windows

For all its strategic seriousness, Fort Stark also generated the kind of local lore that outlives any battle. The big coastal guns were powerful enough to rattle the whole neighborhood. As one account passed down near the site recalls, the first time the largest guns were fired, the concussion “broke every window and the china in the Wentworth by the Sea Hotel,” the grand resort across the water. The message from the hotel, the story goes, amounted to a firm request never to do that again. It is the sort of detail that turns a pile of old concrete into a place with a personality.

Today, things are a great deal quieter. George Bald, former commissioner of the state Department of Resources and Economic Development, counts Fort Stark among the true gems of the state parks system precisely because it is not a headliner. “Obviously, Hampton Beach and the Flume are big parks, but this is a park that is really sweet,” he told NHPR. The appeal is not amenities or attractions. It is the setting, the history, and the quiet.

From neglect to a volunteer rescue

The transition from military base to public park was not smooth. After the fort was decommissioned and turned over to the state in the 1980s, there was little public money available to keep it up, and the site suffered for it. “For a while, it was quite hard to maintain a good presence here and a lot of stuff got overgrown,” Bald recalled. The state’s inattention drew complaints from residents who wanted better for the property. “People were complaining that the state wasn’t doing enough, and so it really became that we had to do something,” Bald said, “but fortunately there’s a wonderful volunteer organization in New Castle.” That community involvement, which took hold around 2007, helped clear the way for Fort Stark’s transformation from a fenced-off relic into a place to relax.

Anyone who grew up nearby before the cleanup remembers a wilder version. Jason Goddard of Portsmouth spent his childhood playing at the fort back when it was essentially abandoned and unsupervised. “There wasn’t a fence to be seen, not a door was welded shut yet, and this fort was at our disposal, and it was like living in the Goonies movie,” Goddard recalled. “We would be going through tunnels with torches that we made. We’d be sliding down cables to lower levels and doing stuff that if our parents were aware, they would have absolutely had heart attacks.” The site is safer and more managed now, but that sense of adventure still clings to the tunnels and stairwells.

A free window on American history

What makes Fort Stark worth a summer detour is the accessibility of it all, in every sense of the word. The crumbling, graffiti-covered pillboxes and batteries still keep a kind of vigil over the shore, and for Bald that is exactly as it should be. “Anyone can come,” he said of the fort. “It doesn’t matter if you’re a multi-millionaire or you’re making minimum wage, it gives you access to a spectacularly beautiful spot.” In a state where oceanfront access can be expensive and crowded, a free historic site with panoramic water views is a genuine public asset.

For visitors building a Seacoast itinerary around the nation’s 250th, Fort Stark pairs naturally with the region’s other layers of history. It sits near the same working waterfront that our coverage of the Navy’s half-billion-dollar investment in Portsmouth Naval Shipyard explores, a reminder that the Piscataqua has been a military artery for generations. Those interested in the fuller, more complicated American story can trace it through our reporting on how New Hampshire communities are reading Frederick Douglass as the nation turns 250 and on how the state’s Black Heritage Trail is reframing the semiquincentennial in Portsmouth.

The practical pitch is simple. Pack a lunch, point the car toward New Castle, and give yourself an hour or two to walk the batteries, read the interpretive signs, and watch the boats work the channel. The wind and the waves are free, the parking is easy, and the history is real. For a state that will spend this summer celebrating 250 years of American independence, few places let you feel that stretch of time as directly as a coastal gun battery that has been standing guard, in one form or another, since 1746.

Where is Fort Stark located?

Fort Stark is a state historic site on Jerry's Point at the southeast corner of New Castle Island in New Castle, New Hampshire. It sits on a peninsula overlooking the Piscataqua River, Little Harbor, and the Atlantic Ocean, offering wide views of the Seacoast.

How old is the fort?

The point was first fortified in 1746 as Battery Cumberland with nine 32-pounder cannons. A new battery was built in 1794, militiamen garrisoned it during the War of 1812, and the modern concrete fort was constructed between 1901 and 1905, with minefield-control facilities added from 1907 to 1909.

Is Fort Stark free to visit?

Yes. Fort Stark is a state historic site that is open to the public, and former state parks official George Bald emphasized that it gives everyone, regardless of income, access to a beautiful coastal spot. Visitors can walk the old batteries and take in the ocean views.

Who maintains the site today?

After the fort was turned over to the state in the 1980s, it fell into disrepair due to limited public funding. A volunteer organization in New Castle became involved around 2007 and helped restore the site into the accessible park it is today.

What is the story about the Wentworth by the Sea Hotel?

According to local lore recounted at the site, the first time Fort Stark's largest coastal guns were fired, the concussion broke every window and the china at the nearby Wentworth by the Sea Hotel, prompting a request never to fire them like that again.
