Sullivan County

Sullivan County is an administrative division in southwestern New Hampshire that encompasses hilly terrain with mountain ranges and multiple lakes throughout the region. The county is made up of fifteen towns, with Newport serving as the main administrative center.

The county was established in 1827 and named after John Sullivan, a military officer who commanded forces during the American Revolutionary War. Following its creation, the region grew as an agricultural area and later developed along important trade routes.

Each town in the county maintains its own traditions reflected in the way residents gather at local markets and community events throughout the year. These celebrations bring neighbors together and show how people have shaped their communities over generations.

Newport is home to the County Commissioner's Office where visitors can find information about public services and administrative matters for the region. The area is accessible by car, and small towns scattered throughout offer basic services and supplies.

The Cornish-Windsor Bridge crosses the Connecticut River and remains one of the longest covered wooden bridges still in use, displaying 19th-century engineering craftsmanship. Visitors can walk across this structure and appreciate the construction methods that have kept it standing for over 150 years.
