History of Dover New Hampshire begins with Indigenous homelands, the Cocheco and Bellamy rivers, seventeenth-century English settlement, farming, and water-powered industry. Located in Strafford County in southeastern New Hampshire, Dover developed near waterways connecting the interior with the Piscataqua region. Mills, shipbuilding, textiles, immigration, railroads, and manufacturing later shaped the city.
Abenaki and other Indigenous peoples lived throughout the region long before Dover developed. Rivers, forests, wetlands, and coastal waterways supported fishing, hunting, agriculture, travel, and trade. Therefore, Dover’s history begins long before permanent English settlement.
The Cocheco River became one of Dover’s defining geographic features. Its falls provided valuable waterpower for mills and manufacturing. Additionally, the river connected with the Piscataqua watershed and regional transportation routes.
English settlers established a permanent community at Dover Point in 1623. The settlement was among the earliest English communities in present-day New Hampshire. Fishing, farming, timber, and trade supported its early economy.
The Dover Point area was historically associated with Edward and William Hilton. Early settlement concentrated near the waterways, where transportation was easier. Over time, development gradually spread toward other parts of present-day Dover.
The community passed through several early names, including Hilton’s Point and Northam. It eventually became known as Dover during the seventeenth century. The name has remained associated with one of New Hampshire’s oldest communities.
Relations between English settlers and Indigenous peoples became increasingly violent as colonial settlement expanded. Dover experienced attacks and warfare during periods of regional conflict. These events became part of a much broader struggle over land, sovereignty, and colonial expansion.
Settlement gradually concentrated around Cocheco Falls because of its waterpower potential. Mills processed timber, grain, and other products. Therefore, the falls helped shift Dover’s economic center away from the earliest settlement at Dover Point.
Dover’s access to navigable waterways encouraged shipbuilding and maritime commerce. Local timber supplied an important raw material. Meanwhile, vessels connected the community with Portsmouth and wider Atlantic markets.
Large textile operations developed around Cocheco Falls during the nineteenth century. The Cocheco Manufacturing Company became a major local employer. Massive brick mill buildings transformed the riverfront and accelerated urban growth.
Additional manufacturing businesses expanded Dover’s industrial economy. Factories produced textiles and other goods for regional and national markets. As a result, factory work became central to the city’s nineteenth-century development.
Industrial employment attracted immigrants from Ireland, French Canada, and other regions. Families established homes, churches, businesses, and community organizations. Additionally, immigrant workers became essential to Dover’s manufacturing economy.
Railroad service connected Dover with Portsmouth, Boston, Portland, and other New England communities. Trains carried passengers, raw materials, and manufactured goods. Consequently, Dover became an important transportation point in southeastern New Hampshire.
Dover incorporated as a city in 1855. Municipal government expanded alongside population and industrial growth. Meanwhile, downtown developed with stores, banks, churches, schools, and civic buildings.
The Woodman Museum opened in Dover in 1916. Its collections document local history, natural history, decorative arts, and military subjects. Historic buildings within the museum complex preserve additional connections with Dover’s past.
New England textile manufacturing declined during the twentieth century. Dover’s mills eventually lost much of their original industrial role. However, the surviving buildings remained prominent features of the downtown landscape.
Former mill buildings along the Cocheco River have been adapted for offices, residences, restaurants, and other businesses. Reuse preserved important industrial architecture while supporting downtown activity. As a result, the historic mill district continues to shape modern Dover.
Dover contains historic resources from several periods of development. Dover Point preserves connections with seventeenth-century settlement, while downtown reflects later commercial and industrial growth. Additionally, historic homes and public buildings document generations of community life.
Local museums, libraries, preservation groups, and government programs maintain records of Dover’s history. The Dover Public Library preserves local materials, while the Woodman Museum maintains extensive collections. State preservation resources provide further information about historic properties throughout the city.
Dover grew from Indigenous homelands and a seventeenth-century river settlement into an important New Hampshire manufacturing city. The Cocheco River, shipbuilding, textile mills, immigration, and railroads shaped its development. Today, historic districts, reused mills, museums, and archives preserve important chapters of Dover history.
