These Texas Recorded Historical Landmarks are amazing looks into the past of Mesquite.Opal Lawrence Historical Park is listed on the National Register of Historic Places, is a Recorded Texas Historic Landmark, and recognized as a Century Family Farm by the Texas Department of Agriculture.

Florence Ranch Homestead is an outstanding example of late 19th century rural Texas architecture and early pioneer ranching. Built-in 1871, Florence Ranch Homestead was established two years before the township of Mesquite and grew along with the city.
