It is believed the name Llantwit Fardre is derived from an old Welsh Language name meaning The Church of St Illtud (Llantwit), on the Home Farm of the Prince (Faerdref) and relates to the land surrendered to the prince of the District by his subject to provide him with an income. Saint Illtud was a 5th-century Celtic priest who built his second church roughly in the area where the present church stands. He was later famed as the Saint of the Five Keys of youth, learning, chivalry, priesthood and knighthood.
Industrialisation began in Llantwit Fardre in the late 17th century with the introduction of stone quarrying and coal mining. With the decline of coal mining the local populace tend to commute to work.
