Ysgol Gyfun Cwm Rhymni is a Welsh-medium school situated in the village of Fleur-de-Lys in the Rhymney Valley. Cwm Rhymni was founded in 1981 with just over 150 pupils and has since grown to 1,684 pupils with 1,164 at the Gellihaf campus and 520 at Y Gwyndy (September 2018). The school's motto is “Tua'r Goleuni” (Towards the Light) and its badge is a dragon rampant. The school is traditionally represented by the colours red and black. A new campus for Ysgol Gyfun Cwm Rhymni opened in Caerphilly Area in 2013 for years 7 through 11; Ysgol Gyfun Cwm Rhymni – Safle'r Gwyndy, due to the demand of a new Welsh Medium school. The previous school is now called Ysgol Gyfun Cwm Rhymni – Safle Gellihaf so it is not confused with the other campus. The original Cwm Rhymni school was based in Aberbargoed (years 7-8) and Bargoed (years 9-13). Source: Wikipedia (en)
