The college (which originally only included the main campus at Rhos-on-Sea) was opened as Llandrillo Technical College by Prince Philip, Duke of Edinburgh, on 23 June 1965. The word "Technical" was removed from the name of the college in response to the college's shift towards teaching academic as well as vocational subjects. The name Coleg Llandrillo Cymru was adopted around 2002 and was intended to imply that the college is for the whole of Wales. Since its merger with
Coleg Menai, it is now known as Coleg Llandrillo.
2010 merger Coleg Llandrillo formally merged with
Coleg Meirion-Dwyfor on 1 April 2010. The merged college (which retained the Coleg Llandrillo name) was located at nine campuses across three counties. Although the colleges had merged their management and administration, the Coleg Meirion-Dwyfor campuses retained the
Coleg Meirion-Dwyfor name.
2012 merger In April 2012, Coleg Llandrillo Cymru (which included Coleg Meirion-Dwyfor) merged with
Coleg Menai to form
Grwp Llandrillo Menai. With 20,000 students across four counties Grwp Llandrillo Menai became Wales' largest further education institution. Coleg Llandrillo Cymru became known as Coleg Llandrillo. ==Campuses==
