On part of one downtown block, about 1.2 acres which had at one time the largest concentration of oil wells in the world, producing more than 2.5 million barrels of oil. All but one of the derricks were dismantled in the early 1960s. The original derrick and twelve new ones, a restored pumpjack, and a granite monument to pioneer oil families of East Texas, and brick walkways restore this historical project dedicated to the oil boom of the 1930s.
