On a beach in Devon, a huge bell has been set up to sound when the tide is coming in and going out.
One of 13 bells in England, Wales, and Scotland that highlight global warming and rising sea levels is the Time and Tide Bell in Brixham.
The structure, which is more than 6 feet (1 point 8 meters) tall, was put in place, according to the Devon installation's organizers, with the help of "incredible" local support.
A clapper that is now moved by the tide rings the bell.
On 6 June, the £20,000 structure was erected on a rock bed at Breakwater Beach.
More than 20 people, including members of a nearby rowing club, contributed to its installation.
The top bell, which weighs 0 tonnes, and the green oak supporting structure make the bronze bell "really heavy," according to Pauline Neal of the Friends of Brixham Time and Tide Bell. The larger bottom portion of the bell weighs approximately 1.5 tonnes.
But she went on to say that it was "just incredible" that the bell was now on our beach and that "local support had been invaluable.".
"It was very difficult, but with the aid of Brixham gig club members we were finally able to physically move and fix the bell to the rock bed," she said. " .
Marcus Vergette, a Devon artist, came up with the concept for the national project, and the first bell was installed at Appledore in North Devon.
Another has been set up at a beach in Par, Cornwall, which is located elsewhere in the South West.
