Among the many cannon on display is one fake. In the early 1900s, a 4-pound British cannon thought to be of the colonial era was lodged halfway into the middle of Longitude Alley, supposedly to prevent dray carriages from using the narrow passage. In 1933, the City decided to unearth the cannon and relocate it in White Point Garden at the intersection of a projected Church Street extension and Murray Blvd. The residents of Longitude Lane were unhappy at the loss of their relic, and demanded its return, but the City was not moved. Meanwhile, a prankster hired a foundry to create a fake cannon of the same era. He aged the cannon by submerging it in water for six months at his dock and then sold it to an antique store in Beaufort, South Carolina. When it was "discovered" there, it was bought by a visitor from the North and brought to Charleston. The buyer offered it to the residents of Longitude Lane to replace their cannon, but they rejected the offer, instead demanding the original cannon. The City, however, believed the cannon to be genuine and acquired it for display too. The cannon fooled many people, but it suffered a telltale anachronism: because the foundry did not have the tools to fabricate an actual cannon, the foundry instead poured molten metal around a section of cast iron pipe even though cast iron pipe was not used even in large cities until the 19th century. The Longitude Alley cannon stood across the park at the intersection of Church St. and South Battery; it was removed by the City following vandalism (possibly an attempted theft) and then either lost or stolen. It has not been seen since.
