Suffolk County

Suffolk County covers the eastern portion of Long Island, extending from suburban areas to the island's far tips where beaches and farmland shape the landscape. Administration spreads across several locations, with courthouses and agencies divided among different towns.

Founded in 1683 under English colonial rule, the name marked the connection to Suffolk County in England. During the Revolutionary War, the area remained under British control and rejoined the new nation only after the conflict ended.

The eastern half of Long Island carries names of English origin that recall early settlement, while daily life today revolves around beaches and farm stands. Local communities preserve maritime traditions visible in harbor festivals and oyster farming along the coastline.

Most administrative services operate from Riverhead and Hauppauge, where visitors can find information and assistance. Public transit connects the larger towns, while remote areas are best reached by car.

Two major research facilities sit within the borders of this area, contributing to science in physics and veterinary medicine. These laboratories employ thousands of people and shape the local economy alongside tourism and agriculture.
