What Does “Cofiwch Dryweryn” Mean?

In Welsh, Cofiwch Dryweryn literally means “Remember Tryweryn”. This phrase, first painted on a simple cottage wall in Ceredigion in the early 1960s, has become a symbol of remembrance, resistance, and Welsh national pride.

The original Cofiwch Dryweryn words were painted on a wall of an uninhabited cottage near to the small village of Llanrhystud, Ceredigion. This village is some 10 miles south of Aberystwyth. The words Cofiwch Dryweryn have become a self-fulfilling prophecy - without question what occurred in the Tryweryn valley in the 1950's and 1960's will always be remembered!

The Flooding of the Tryweryn Valley

In the 1950s and 1960s, plans were made by Liverpool City Council to build a large reservoir in the Tryweryn Valley in north Wales to supply drinking water for Liverpool and Wirral. A private Act of Parliament was passed in 1957, bypassing Welsh local authorities and public consultation.

As a result:

  • The village of Capel Celyn, one of the last exclusively Welsh-speaking communities in Wales, was flooded in 1965 to create Llyn Celyn reservoir.
  • Homes, farms, school, post office, chapel and cemetery werelost under water, and residents were forced to leave lands their families had lived on for generations.
  • The event generated widespread opposition across Wales, seen by many as an attack on the Welsh language and culture.

 

Llyn Celyn submerged the village of Capel Celyn, a village some 6 miles north of Bala in north Wales

 

Origins of the Slogan

In response to this loss, Welsh author and cultural figure Meic Stephens (with Rodric Evans) painted the first Cofiwch Dryweryn message on a ruined farmhouse wall near Llanrhystud on the A487 coastal road.

Despite the humble original, the mural took on lasting significance, reminding people locally and internationally not to forget Tryweryn. It is interesting to note that Meic Stephens, a prolific author described these two words as "my most famous statement, my best-known poem, my most eloquent speech, and my most influential political act.

   

Official Apology and Modern Reflection

In 2005, Liverpool City Council issued a formal apology for the hurt caused by the Tryweryn project, acknowledging the insensitivity of the original decision that led to Capel Celyn’s destruction, although the apology received mixed reactions in Wales. It is an understatement to say that the apology was not universally accepted in Wales!!!

Legacy and Cultural Importance

Over the decades, Cofiwch Dryweryn has become more than a piece of graffiti:

  • It is widely seen throughout Wales and beyond, including in cities and communities outside Wales. The sign has been seen in places from London, New York and Sydney to the Yr Wyddfa (Snowdon) Summit and the Falkland Islands!
  • It stands as a symbol of Welsh identity, cultural resilience, and linguistic pride.
  • The wall has been restored and repainted multiple times, especially after incidents of vandalism, reflecting ongoing local commitment to preserving the message.
