Description:
"On part of one downtown block, about 1.2 acres, once stood the greatest concentration of oil wells in the world, producing more than 2.5 million barrels of oil. All but one were dismantled in the early 1960s. The original derrick and 36 new ones, a restored pumpjack, a granite monument to the pioneer oil families of East Texas, and brick walkways make the park a monument to the oil boom of 1930s."
