Chambers, small stone buildings of indefinite function, dot the hilltops and roadsides of New Hampshire. Some believe they are the Acworth chamber
remains of colonial root cellars. Others argue that they are Native American ceremonial structures or Celtic in origin. Some New Hampshire chambers are listed below.


Acworth Chambers

Located on a hilltop in Acworth are many small enclosures and stone rows that have excited the curiosity of people for the last century. William Goodwin’s 1947 book History of Great Ireland in New England compared the site in Acworth to similar sites in Europe and hypothesized that the chambers and stone rows were built by Irish monks settling the northeast centuries before the arrival of Columbus. Later ideas claim different functions for the site, including Native American ceremonial structures, colonial storage chambers, and the remains of fox hunting traps.

The Danville ChamberDanville Chamber

The Danville Chamber is relatively easy to find and is, at this time, accessible to the public. Follow Route 111A to Hersey Road. Hersey Road bears sharply to the left. Follow it to the end and park out of the way of the DPW facility access. Walk down the dirt road and look for a trail to the left; follow the trail along the bedrock outcrop and look for the chamber built into the side of the hill.

Derry ChamberDerry chamber

The Derry chamber is located along an abandoned railroad track in Derry and most likely of modern construction. Look for drill marks along the rocks at the bottom of the interior of the chamber.

To get the Derry chamber follow Windham Road in Windham to Windham Depot Rd. Turn onto Windham Depot Rd and look for rail trail parking immediately on your right. Once out of your car follow the paved area to the rail trail head. DO NOT follow the main trail, but look for an unpaved side trail off to the left. Follow this trail for 0.2 miles. The chamber will be immediately off the trail to the left.


 Natural Features

Most of New Hampshire’s unusual rock formations are known to be natural; some argue that these formations are the work of early man. Glaciers have rearranged these heavy stones so that they appear in almost impossible-to-believe formations. Man, however, may have also enhanced the work of nature.

Perched Boulders

Perched boulders, also known as balanced rocks, are places of natural beauty that capture the imagination of many today and may have been significant to New Hampshire’ first inhabitants. Perched boulders in New Hampshire may be found in Andover, Antrim,  Pillsbury, Raymond, and Woodstock  as well as in other places around the state.

Rocking Stones

Early accounts of New Hampshire include many descriptions of “rocking stones”, boulders that move easily on their base when pushed or disturbed by the wind. The most famous of these, the Durham rocking stone, is described below:

“A large detached block of granite, in the south-east part of this town, was formerly placed in a very singular situation. Its weight was sixty or seventy tons, and it was poised so exactly upon two other stones, as to be visibly moved by the wind. It was some years since dislodged from this extraordinary position by the barbarous curiosity of some visitors.” Hayward, John. A Gazetteer of New Hampshire Containing Descriptions of All the Counties, Towns, and Districts in the State. John P. Jewett: Boston, 1849.

Other rocking stones have been described in historical records in Andover, Goffstown, Hanover, Meredith, Newport, and Warren.



Native American Rock Sites

Jefferson petroglyph

Most early historical accounts attempted to write the Native peoples of New Hampshire out of its history sometime in the Eighteenth century. Reduced by disease, driven away from their homelands and into Canada, or forced to assimilate, the Native population of New Hampshire seemed to disappear. Under these circumstances it became easy for many to claim that New Hampshire was never home to any substantial Indian population, a view that still exists in many parts of the state today.

If one looks closely, though, reminders of this vibrant and substantial culture can still be seen in woods and backyards throughout the state. Petroglyphs, grinding stones, and other stone remains are still being found and recorded.   NEARA is attempting to do its part to preserve and document the remains of this once omnipresent Native New Hampshire  below.

Pictures in stone are often hiding in plain sight. Look closely at large boulders or rocks located in significant places and you may see one jump out from the shadows of the rock.




Laconia cupules



Cupules, circular indentations pecked or ground into bedrock or boulders, have long been associated with Native cultures of North America, and are found in several locations across the northeast, including New Hampshire. One of these sites is in Laconia at Endicott Rock Park.

The original charters of Massachusetts and New Hampshire stated that the border between these colonies was to be set three miles north of the Merrimack River. However, subsequent reports indicated that the Merrimack River ran north-south, not east-west, as first believed, and a border dispute between the states soon ensued.

In 1652 Governor Endicott pressed his advantage and sent members of the Massachusetts Bay Colony in search of the source of the Merrimack River. With the help of their Indian guides, these men made it to Weirs Beach, or Aquedocton, in Laconia, the site of a large Indian settlement, and carved their initials and the name of Governor Endicott upon a large rock in the channel of the Winnipesaukee River, laying claim to the surrounding land for Massachusetts.

Long thought of as a significant historic place, Endicott Rock has recently been reevaluated to include the cupules that mark its surface. These cupules, located on a prominent rock near a large fishing village, must have been significant to the Native community of Aquedocton and the guides who led the colonists to the source of the Merrimack River.


Franklin grinding stone

Grinding Stones

Grinding stones are believed to have been used by Native peoples to grind their corn.This one is located in Franklin at the corner or Dearborn and Central Streets.









Thorvald’s Rock Hampton, NH

Across the street from the Tuck Museum in Hampton is a boulder covered with lines and scratches once thought to be a runic inscription marking the site of the burial of Thorvald, an early Viking explorer of “Vinland”. Encased in a concrete enclosure and set beneath iron bars, this rock was once so important to the residents of this town that it sparked the formation of the local historical society. Now debunked and widely thought of as a fake, Thorvalds’ rock still attracts visitors to the Tuck Museum.

Hampton’s Lane Memorial Library is a great source for more stories on Thorvald’s Rock.


 Rock Piles

New Hampshire is the “granite state” and one is not surprised to come across stone piles while Northwood rock pileBear Brook State Park rock pile
walking in the woods. Some are clearly the remains of long-abandoned farms. Others, located on land that no one would ever farm or built with obvious design, seem more mysterious. Are they clearing piles left behind on long-abandoned farms? Are they burial sites for early colonists? Or are these the remains of Native American ceremonial sites?

Our goal in NEARA is to document and preserve as many of these sites as possible until such time as we can determine their origins and functions. Please help us preserve them by reporting them to NEARA and by leaving them intact.
