What stands out about Mansfield’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
R.E. Darling named Mansfield in 1905 after his hometown of Mansfield, Ohio. Mansfield's land was purchased and first developed in 1909 by the Great Northern Railway. Mansfield was officially incorporated on February 23, 1911.
By 1914, the town had grown substantially, and had acquired two hotels, a bank, a doctor's office, and many more amenities. What had started as a town based on agriculture and the railroad had grown into a popular resort destination.
