The Big Well, in Greensburg, Kansas, USA, is a water well that was designed to provide water for the Santa Fe and Rock Island railroads. It was built in 1887 at a cost of $45,000, and served as the municipal water supply until 1932.
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.
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 since 1972.
Visitors entered the well for a small fee, descending an illuminated stairway to the bottom of the well.Visitor center
The well had a visitor's center detailing the history of the well's construction. On May 4, 2007, a tornado hit Greensburg, destroying the center.
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, Kansas.
