Manchester's flag features a white field with the municipal seal in color at the center. The seal has a black ring bordered in gold. In the ring, "CITY OF MANCHESTER" curves at the top, and "INCORPORATED JUNE 1846" curves at the bottom, all in gold.
The seal itself contains three sections with various symbols representing Manchester's industrial heritage: a waterfall (the Amoskeag Falls on the Merrimack River), factory buildings, and industrial equipment. The arm holding the hammer represents industry. The motto "Labor Vincit" translates as "Labor Conquers."
Manchester was once the textile capital of the world. The Amoskeag Manufacturing Company, founded in 1831, became the largest textile complex in the world: 30 brick buildings, 15,000 employees, 700,000 spindles producing 50 miles of cloth per hour. The factories lined the Merrimack River for miles.
The collapse came in 1936 when Amoskeag closed, throwing the city into economic chaos. But Manchester survived, diversifying into technology, financial services, healthcare. The largest city in New Hampshire. The hammer of the seal keeps striking.
