The Hilltop City is the smallest of the Tri-Cities and the smallest geographic area of the thirteen cities in New Hampshire. Somersworth, Rollinsford, and the neighboring Maine communities were known as Newichawannock by the Abenaki. Originally incorporated as part of Dover in 1641, Somersworth and what is today Rollinsford separated in 1754, with Rollinsford later being independently incorporated in 1849 and Somersworth becoming a city in 1893. Throughout the 19th century Somersworth’s location on the Salmon Falls River became home to carpentry, marble, textiles, sawmills and piping  industries. Although the city’s population declined as it entered the 20th century, it has found new life as a diverse community and home to the Little Indonesia Community Center.
