In short: Founded in 1655, Brookhaven evolved from a small collection of agricultural hamlets into a sprawling suburban powerhouse. Today, this Suffolk County town balances its deep colonial roots and Revolutionary War history with cutting-edge scientific research, hosting world-class laboratories and preserving unique landscapes that span from the North Shore to Fire Island.

The origins of Brookhaven date back to 1655, when agents from New England and Southold purchased an eight-square-mile tract from the Setalcott tribe. Initially known as Setauket, the area was formally established under the name Brookhaven in 1666 via a patent from Governor Richard Nicholl. By 1686, the town had instituted a representative government. During the American Revolutionary War, the region became a strategic theater, most notably serving as the base for a spy network that provided critical intelligence to General George Washington.

The town's economic identity shifted significantly over the centuries. Early residents relied on farming, fishing, and whaling to sustain their communities. By the 19th century, the local economy diversified into shipbuilding and the cordwood industry. In the modern era, Brookhaven transformed into a hub for technology and research. It is home to the Brookhaven National Laboratory, established in 1947, which has been the site of four Nobel Prize-winning physics discoveries. The town also hosts the original laboratory of Nikola Tesla and the site of Radio Central, which was the world's first commercial overseas transmitting station.

Spanning over 325 square miles, the town features 125 miles of coastline and includes significant protected areas like the Pine Barrens and portions of the Fire Island National Seashore. Preservation remains a priority, with the town maintaining 16 historic districts and dozens of designated landmarks. Community-led initiatives, such as the restoration of the Hobbs Community Farm, highlight a commitment to heritage and local sustainability. Whether through the annual events at the historic Longwood Estate or the ongoing scientific work at its research centers, Brookhaven continues to bridge its agrarian past with its role as a leader in 21st-century innovation.
