Cofiwch Dryweryn (English: "Remember Tryweryn") or Y Wal Cofiwch Dryweryn (English: "The Remember Tryweryn Wall") is a graffitied stone wall in Llanrhystud, Wales. Author and journalist Meic Stephens originally painted the words onto the wall in the early 1960s following the decision by the Liverpool City Council to flood the Tryweryn Valley to create a reservoir. Due to its prominent location, stark message, and history of repeated vandalism, the wall has become an unofficial landmark of Wales. The phrase "Cofiwch Dryweryn" has itself become a prominent political slogan for Welsh nationalism, appearing on T-shirts, banners, and as replica murals.
In a 2006 interview, Stephens stated that he "didn't choose the spot for any particular reason" and that he "didn't expect it to turn out any more iconic than any other slogan."
Following parliamentary approval, Liverpool City Council pursued the flooding of Tryweryn Valley without the consent of Welsh authorities and against the wishes of most Welsh Members of Parliament. The council also failed to respond to formal planning inquiries presented by residents to explain their concerns with the proposal. Despite protests in Liverpool, London, and Wales, the valley was flooded in 1965, and several centuries-old communities such as Capel Celyn were lost.
In 1962 and 1963, Meic Stephens, a Welsh author and scholar, had painted numerous slogans across the South Wales Valleys. In response to the upcoming flooding of the Tryweryn Valley, Stephens decided to paint "Cofiwch Tryweryn" (sic), Welsh for "Remember Tryweryn", onto a rock. He drove around Wales with his friend Rodric Evans to find a suitable location, after which he spent fifteen to twenty minutes painting the message. The wall Stephens used is part of a ruined cottage named Troed-y-Rhiw. Because the original Cofiwch Tryweryn is grammatically incorrect, all subsequent restorations of the wall have repainted the message correctly as Cofiwch Dryweryn.
Vandalism and protection
Since its first appearance, the message has been both vandalised and restored on numerous occasions. In 1991 schoolboys Rhys ap Hywel and Daniel Simkins painted the wall white, rewrote the message, and added their initials. In 2003, the Ceredigion Urdd repainted the phrase onto the wall as part of a show commemorating the events of Tryweryn at Theatr Felinfach. By 2007, a section of the wall had fallen and the writing had been replaced with stencilled white letters on a red background. In May 2008, the message was altered to Angofiwch Dryweryn (English: "Forget Tryweryn"; correct spelling Anghofiwch). The monument was again defaced in April 2010, prompting a spokesperson for the Welsh Government to state their disappointment with the defacement after recent attempts to preserve the wall. Due to wall's history of vandalism and its state of decay, many people wanted the wall to be designated as a national monument as a means of protection. Despite the launch of a fundraising campaign to achieve this goal, the wall did not receive a designation, and was further vandalized in 2013 and 2014.
In 2017, the words Cofiwch Aberfan 1966 ("Remember Aberfan 1966") were added underneath the original message, referring to the Aberfan disaster. After a restoral of the wall in 2018, it was defaced again in February 2019, though was restored within twenty-four hours following a social media campaign. The incident saw renewed calls for its protection, most notably from Bethan Sayed, Plaid Cymru's spokesperson for Heritage, Welsh Language and Sport. On 11 April 2019, i’r Gâd! ("to battle" or "to arms!") was added at the base of the mural, with the top section of the wall containing the word Cofiwch (remember) being demolished the next day. The wall was rebuilt and repainted on 13 April by a group of eight volunteers. In the subsequent days, a second wall next to the original was painted with Fe Godwn Ni Eto (We'll rise again) and the campaign organisation YesCymru reported that over fifty new Cofiwch Dryweryn murals had been painted throughout Wales. In London, the message was displayed on a banner at that month's London Marathon, in addition to signs with the message being displayed at Downing Street and Whitehall. By the end of April, it was estimated that over a hundred murals with the message had been painted globally. Dyfed-Powys Police responded to the vandalization by placing a CCTV camera at the site, stating that they were treating the incident as a hate crime.
