A settlement has existed on this site from at least the beginning of the 6th century, when the poet [[Aneirin|Aneurin]] wrote of "the white houses of Glamorgan" when referring to Llantrisant.<ref name="Freemen1">{{cite web |title=Llantrisant timeline |url=http://www.llantrisant.net/timeline.htm |access-date=30 August 2008 |publisher=Llantrisant freemen website |year=2006 |work=Llantrisant Town Trust |url-status=dead |archive-url=https://archive.today/20120905181615/http://www.llantrisant.net/timeline.htm |archive-date=5 September 2012 }}</ref> It was seized around 1246 by [[Richard de Clare, 6th Earl of Gloucester|Richard de Clare]], who built [[Llantrisant Castle]].

In 1346, Llantrisant was granted a [[royal charter]] months before the archers from the town helped [[Edward the Black Prince]] win a victory against the [[French army]] at the [[Battle of Crécy]]. The Llantrisant [[longbow]] men were pivotal in the adoption of the [[English longbow]] as the missile weapon of choice for the English crown during the [[Middle Ages]].

Llantrisant was one of the eight boroughs constituting the Glamorgan borough following the [[Laws in Wales Acts 1535 and 1542|Act of Union]], a status it held until 1918.
