The area that became Mansfield was originally known as Walnut Creek. In 1857 two business partners, Ralph S. Man and Julian B. Field, relocated to the area to build the first steam-powered gristmill in North Texas. The settlement that grew up around the Man and Feild Mill was named for the two men, with the original spelling of the town name as "Mansfeild". Man’s home, begun in 1865, is the oldest surviving structure in the city. The home was restored by the city of Mansfield and opened to the public as the Man House Museum in 2020.
Other heritage sites in Mansfield include Farr Best Theater and the Mansfield Historical Museum and Heritage Center.
The city was named the official Pickle Capital of Texas in 2013 because the Best Maid Pickles pickling facility is located there. The company grew to be the largest pickle producer in the state and the third largest in the nation.
Today Mansfield is a growing city with a rich heritage and bright future, and is recognized as one of the best places to live, work and play in the country.
