Shibboleth (artwork)

Shibboleth by Doris Salcedo was a £300,000 installation, the eighth commission in the "Unilever Series" (sponsored by Unilever), which takes place annually in the Turbine Hall, the main entrance lobby of Tate Modern in London. Salcedo's installation took the form of a 548-foot (167-metre) long, meandering crack in the floor of the Turbine Hall, a hairline crack at one end which expanded to a few inches of width and around two feet of depth at the other. The crack was made by opening up the floor and then inserting a cast from a Colombian rock face. The work has gained the nickname "Doris's crack". ==Health and safety==

Prior to the exhibition's opening, the Tate's head of safety and security, Dennis Ahern, had warned of the danger of visitors tripping on the crack "with the potential for significant leg injury," but that "physical protection measures which would normally be applied to a gap of this nature are not deemed appropriate due to its artistic nature." In some places it was wide enough for a small child to fall into. mostly minor, but four of the accidents were reported to the Health and Safety Executive. ==See also==
