It was built in 1887 at a cost of $45,000 to provide water for the Santa Fe and Rock Island railroads, and it served as the municipal water supply until 1932. It was designated a National Museum in 1972; in 1973 it was awarded an American Water Landmark by the American Water Works Association. Under the name of "Greensburg Well," it has been listed on the National Register of Historic Places (NRHP) since 1972.
It is billed as the world's largest hand-dug well, at 109 feet (33 m) deep and 32 feet (9.8 m) in diameter. The Well of Joseph in the Cairo Citadel at 280 feet (85 m) deep and the Pozzo di S. Patrizio (St. Patrick's Well) built in 1527 in Orvieto, Italy, at 61 metres (200 ft) deep by 13 metres (43 ft) wide are both actually larger.
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 was displayed temporarily at the Sternberg Museum of Natural History in Hays, Kansas. It has returned to the reconstructed museum site.

- Other hand-dug wells are much deeper, such as the Woodingdean Water Well in Brighton, England, but the Big Well's diameter gives it a greater total volume.
