Ysgol Treffynnon (formerly Holywell High School)[3] is an 11–16 mixed, English-medium, community secondary school in Holywell, Flintshire, Wales. Previously it was Holywell Grammar School.
There were 2 buildings which made up the school; Lower and Upper. The Lower building catered for 11-13 year olds and the Upper building for 14-18 year olds and included the Sixth Form. The upper building was demolished in the mid-1990s to make way for a new housing development and the Lower building was remodelled to accommodate the whole school into one building.
