In 1908 a Welsh eisteddfod was held here in Earlington Park.
The annual international musical eisteddfod (festival) is held here.
In Cathays Park there is also a "gorsedd" or bardic circle of huge monoliths erected in connexion with the eisteddfod of 1899.
They support the Eisteddfod as the promoter and inspirer of arts, letters and music, and are conspicuous among the annual prize winners.
At the castle of Cardigan in 1176, Prince Rhys held a historic bardic entertainment, or eisteddfod, wherein the poets and harpists of Gwynedd and Deheubarth contended in amicable rivalry.
