Remember Tryweryn! In case anyone's wondering what this is about, in the 1960s the Tryweryn Valley in Wales contained a village (Capel Celyn) which was evacuated and the valley flooded to make a new reservoir to provide water for Liverpool. There's a portion of a nearby wall painted with these words.
