Rogers, Poole Silver, and others produced fine-quality silver goods in the city.

Since December 1914, the city of Taunton has provided a large annual light display each December on Taunton Green, giving it the additional nickname of the Christmas City.

The original boundaries of Taunton included the land now occupied by many surrounding towns, including Norton, Easton, Mansfield, Dighton, Raynham, Berkley, and Lakeville. Possession of the latter is still noted by the naming of Taunton Hill in Assonet.
