Pergolas in Stony Brook, NY

Stony Brook was first settled in the late 17th century. It was originally known by the native name Wopowog and then as Stony Brook, with both names likely referring to the interconnected bodies of water at the hamlet’s western edge. It began as a satellite community of adjacent Setauket, New York, the Town of Brookhaven’s first settlement, and its land was included in the initial 1655 purchase from the native Setalcott tribe.

A gristmill was built in 1699 on the water body now known as the Mill Pond. The current structure, which replaced the original in 1751, ground grain into the 1940s and has since been repurposed for public tours. For religious services and education, the hamlet’s original residents had to attend institutions in the neighboring communities of Setauket and St. James. In the latter half of the 18th century, activity began to shift from the mill area north toward the harbor as new residences, a number of which still stand, were constructed.

Stony Brook was a remote area through the 18th century aside for a modest amount of commerce near the mill at the intersection of Main Street and Harbor Road. The community’s development was stalled by its poorly accessible harbor relative to nearby Setauket and Port Jefferson. In the 1840s, local painter William Sidney Mount led a call for the harbor’s dredging. This was completed twice, but after the harbor filled in both times the effort was abandoned. Lacking the resources of its neighboring harbor settlements, Stony Brook based its economy on agriculture and the cordwood industry.
