It is billed as the world's largest hand-dug well, at 109 feet deep and 32 feet in diameter. Only the Pozzo di S. Patrizio (St. Patrick's Well) built in 1527 in Orvieto, Italy, is larger, measuring 61 meters deep (200 feet) by 13 meters wide (42 feet).
Visitors entered the well for a small fee, descending an illuminated stairway to the bottom of the well.
The visitor's center also displayed a Brenham half-ton (1,000 lb, 450 kg) pallasite meteorite recovered from the area. The meteorite was billed as the world's largest single-piece pallasite, but that title is held by other samples. It was reported that the Big Well visitor center was destroyed, and the meteorite was missing on May 7, after an EF5 tornado destroyed the town. The meteorite, which was insured for $1 million, was later located underneath a collapsed wall and is being displayed temporarily at the Sternberg Museum of Natural History in Hays, KS.
