Manchester, with 108,000-plus residents, is New Hampshire's largest city. The town grew up around the Amoskeag Falls on the Merrimack River, which fueled small textile mills through the 1700s. By 1828 Boston investors had bought the rights to the Merrimack's water power and built the Amoskeag Mills, which became a testament to New England's manufacturing capabilities. In 1906 the mills employed 17,000 people and weekly churned out more than 4 million yards of cloth. This vast enterprise served as Manchester's entire economic base; when it closed in 1936 the town was devastated.
Today Manchester is mainly a banking and business center. The old mill buildings have been converted into warehouses, classrooms, restaurants, museums, and office space. The city has the state's major airport, as well as the Verizon Wireless Arena, which hosts minor-league hockey matches, concerts, and conventions.
