The story

How Setauket came to be

From Wikipedia’s history of Setauket.

Read it all →

The name "Setauket" is derived from the historic Algonquian-speaking Setalcott Indians, who had lived in the area before its colonial period.

In 1655, a handful of land-speculating colonists orchestrated the purchase of the Setauket area from the local natives. The region's first European settlers were English migrants from New England. This was the first settlement in what later became the town of Brookhaven, and both the hamlet and town use the 1655 date as their origin. During the 17th century, Setauket was synonymous with the colonial town of Brookhaven.
