Fort Ninigret  Fort Ninigret is a historic fort and trading post site at Fort Neck Road in Charlestown, Rhode Island, built and occupied by European settlers in the seventeenth century. At its 1883 dedication, Commissioner George Carmichael, Jr. referred to it as "the oldest military post on the Atlantic coast." Archaeological excavations have shown that people lived on Fort Neck long before the Europeans arrived, although this was never a large village. But around 1620, many Niantic people settled at this place (cousins and allies of the larger Narragansett tribe), growing corn, making wampum (shell beads used as money in trade with the settlers), and trading with the Dutch and English Colonists for such things as beads, pipes, and copper kettles. Ninigret, for whom the fort was named, was the sachem of the Niantics by the 1630s. Most historians believe that the fort was built by the Dutch West India Company or by Portuguese explorers prior to 1637, in addition to the earlier trading post on nearby Dutch Island. One of the first printed references to Dutch forts in Rhode Island was Samuel Arnold's 1858 "History of the State of Rhode Island". In 1921−22, a European sword and cannon were found at an Indian cemetery near the site, along with many other goods which demonstrate that this was a European fort. The artifacts are now in the possession of the Rhode Island Historical Society. King Philip's War (1675–76) cemented Colonial rule over most of the Indian lands of Rhode Island, but a reservation was set aside for the tribe encompassing much of today's Charlestown. Many Narragansetts had joined Ninigret's people for safety, and soon the name "Niantic" fell out of use. At Fort Ninigret, tribal members lived in wigwams into the 18th century. Nearby stood the European-style house of the sachems, who sold off tribal property to the Colonists to pay their debts. By the 19th century, Fort Neck was the last piece of land held in common by the Narragansett tribe which had access to salt water. In 1883, the state abolished relations with the tribe, instead conferring upon its members the rights and duties of US citizenship. As part of this process, the state transformed the remains of Fort Ninigret into a monument to the 250 years of positive relations between the Narragansett Indians (and their modern descendants) with their non-Indian neighbors.
