Time and Tide Bell is an art project made up of bells, designed by UK sculptor Marcus Vergette and Australian bell designer Neil McLachlan, installed at coastal locations in the UK. The first one was placed at Appledore, Devon, in 2009 and the seventh at Mablethorpe, Lincolnshire in June 2019. As of 2021 at least six further bells are planned, and funding obtained from the National Lottery Heritage Fund in 2018 will allow for up to sixteen bells in all to be installed.
Each bell rings around high tide; the bells provide a reminder that rising sea levels caused by climate change will make the pattern of their ringing change. There is every chance that some of the bells will have to be relocated in the twenty-first century.
Sounds from the bells are featured on Vergette's album Tintinnabulation, released in March 2023 by the label Nonclassical.
The Time and Tide Bell Organisation have commissioned COTIDAL, a film by the Devon-based artist Tania Kovats. The intention is for the completed film to track high tide around the UK, and be 24 hours 50 minutes long. The first hour long chapter premiered in Appledore in September 2022.
