The name of the village occurs in a number of forms: Tonteg, Ton teg, Ton-teg and on some older maps as Ton-têg or Twyn-teg.

[2] Indeed, a farm on the Black Road above the nearby Church Village is named Dan-y-twyn ("Beneath the hill").

The village has a fairly well preserved 12th-century motte castle with an intact moat called Tomen-Y-Clawdd [3] or Coed-Y-Twr.

There are bus services to Beddau, Cardiff, Pontypridd, Talbot Green and Royal Glamorgan Hospital.

The Church Village bypass, as it is known, is built as a single carriageway, with crawler and overtaking lanes around roundabouts and was completed in Autumn 2010.

[12] The ward comprises the eastern strip of the Llantwit Fardre community, including the Tonteg village, Treforest Industrial Estate in the north and Gedrys Farm in the south.
