Newcastle, Texas
Newcastle sits in Young County on the rolling plains of North Central Texas, about 78 miles northeast of Abilene. The town grew up around coal mining in the early twentieth century, and the mines that once supported it eventually closed; the surrounding country is now given over largely to ranching and open range.
