Setauket, NY
County: Suffolk
History

Setauket is a small hamlet located on Long Island, New York, within the town of Brookhaven. The area has a rich history dating back to colonial times.
The name "Setauket" is derived from the Native American term "Sachem's neck," referring to the neck of land on which the hamlet is situated. The Setauket area was originally inhabited by the Setalcott Native American tribe, part of the larger Algonquin Nation.
European settlers arrived in the 17th century, mainly from England, and began establishing farms and settlements. In 1655, settlers purchased land from the Setalcott tribe, officially establishing the town of Setauket. The new settlers thrived due to the fertile soil and proximity to the Long Island Sound.
During the American Revolutionary War in the late 18th century, Setauket became a key center of activity. The area was strategically located between New York City and Connecticut, and its harbor became a vital smuggling and espionage site for the colonial rebels. Notably, Setauket became known for the Culper Spy Ring, a secret intelligence network that provided critical information to General George Washington's Continental Army.
The Culper Spy Ring was primarily operated by local residents, including Abraham Woodhull (code named Samuel Culper Sr.) and Caleb Brewster. They gathered intelligence on British military movements and relayed information through a complex system of codes and hidden messages, often using the local harbor for discreet communication.
The most famous operation carried out by the Culper Spy Ring was the successful capture of British Major General John André in 1780. André was a key officer involved in Benedict Arnold's infamous attempted betrayal of West Point. The intelligence provided by the Culper Spy Ring helped expose André's plot and allowed for his capture, ultimately thwarting Arnold's plan.
After the Revolutionary War, Setauket resumed its role as a primarily agricultural community. In the 19th century, the hamlet experienced growth and development due to its natural beauty and easy access to New York City by ferry. Many wealthy city-dwellers established summer homes in Setauket.
Over the years, Setauket has continued to evolve while preserving its historical charm. Today, it is a picturesque residential community with a deep appreciation for its colonial and Revolutionary War heritage. Historical landmarks, such as the Emma S. Clark Memorial Library and the Caroline Church of Brookhaven, serve as reminders of Setauket's rich past.
In recent years, Setauket has gained more recognition through the popular television series "Turn: Washington's Spies," which depicts the Culper Spy Ring's operations during the Revolutionary War. The show has sparked renewed interest in Setauket's history and brought attention to the significant role the hamlet played in shaping America's early years.
