This area was an important early campsite and watering spot for Indians and pioneer settlers. Two springs formed a natural pool which served as a landmark for wagon trains and cattle drives on the Shawnee Trail. In the 1850s the site was settled by the family of Maj. John Penn of Illinois, who had first visited here in 1848. On July 4, 1882, Penn Springs was the scene of a Confederate reunion of Parson's Texas Cavalry. Owned by Penn Family members until 1895, the springs have continued to play an important role in the development of Duncanville.
