Southwold Earthworks
This prehistoric site was once a fortified village occupied by the Neutral Indians between about 1500 and 1650 A.D. An earth and palisade wall, later strengthened by a second wall, protected a cluster of longhouses. The Neutrals, who emerged as a distinct group within Iroquois culture about 1450, were so-called because they did not participate in wars with traditional Iroquois rivals. This neutrality aroused the ire of the Iroquois confederacy, and Mohawk and Seneca raids brought about the demise of the Neutral nation by 1650.
