The village owes its existence to the development of the coal mining industry during the 19th century. A few shallow shafts and drift was constructed to the rear of Bethesda Chapel at Mynydd Bach. Mynydd Bach was the former name for the village or hamlet. A tramway ran from the mine along Pontardulais road, part of Tycroes road and Heol Brown to the Brown Colliery at Waun y Wernos beyond Heol Brown and then to the sidings of the old Wernos Colliery.
