New Castle, the only town in NH composed entirely of islands, covers approximately 500 acres (.8 square miles) and serves as a scenic residential and recreational community.  New Castle was founded in 1623, chartered in 1679, and incorporated in 1693 during the reign of William and Mary.  Today, in addition to a residential population of slightly more than 1,000, it is home to the Great Island Common recreational park, Wentworth-by-the-Sea Hotel and Spa, a UNH marine research laboratory, a Coast Guard station, and Fort Constitution and Fort Stark state parks.
