The Taunton Green is the city's central square. Early in its history, "The Green" was used as a training ground for militias in the American Revolution. Some say it was also the site of the historic "Liberty & Union"/"Taunton" flag raising in 1774 by the Sons of Liberty, prior to the American Revolution. Since the early 20th century, Taunton Green has temporarily been transformed during the winter holiday season into a grand display of holiday lights, scenes, and extravagant events. This is where and how the city earned its unofficial nickname in the surrounding areas as the "Christmas City."
