IT came, and then it went.
This Cofiwch Dryweryn sign appeared on the seawall at Swansea beach.
Now, after being reported to Swansea Council, it has gone.
Meaning “remember Tryweryn” – in recognition of the Tryweryn valley in north Wales, which was flooded to create a reservoir serving Liverpool – it was one of dozens which appeared across Wales this year.
This spree followed vandalism at the first recorded Cofiwch Dryweryn sign on a stone wall at Llanrhystud, near Aberystwyth.
First it was painted with the word “Elvis”. Then it was partially demolished.
A Swansea Council spokesman said its graffiti removal team had been to work on the seafront and that the Cofiwch Dryweryn sign did not have permission.
A spokesman said: “Street artists are able to work with local groups in the city to develop art murals at locations where permission has been granted.
“We have also established a site at the Recreation Ground for local artists to use legally.”
Cofiwch Dryweryn graffiti has been sprayed in other locations in Swansea, including Clydach – while one even appeared in Chicago.
The UK Parliament’s decision to create the reservoir in the 1960s is regarded as a turning point in the Welsh nationalist and language movement.
BBC Wales has reported that a charity called Tro’r Trai is to take charge of protecting the original Cofiwch Dryweryn sign at Llanrhystud.
Dilys Davies, who bought the sign, said: “This will ensure a secure future for the wall, and the monument will be preserved by the charity for good.”
