Shibboleth (artwork)

Shibboleth was the title of a temporary art installation placed by the Colombian artist Doris Salcedo in the Tate Modern in 2007.

Engineer Stuart Smith, who was responsible for the realisation and installation of the artwork, has since revealed that it was achieved by casting new concrete on top of the original floor slab.

[4] 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.

[5] The Tate placed warning signs and designated staff to monitor the exhibit and hand out leaflets.

[5] In the first month of the display, fifteen people were injured,[6] mostly minor, but four of the accidents were reported to the Health and Safety Executive.
