Thomas Dafydd Llewellyn states that the river "Nantywenallt" formed one of the ancient boundaries of the four
Rhandir of the parish of Aberdare and that there were no workers houses anywhere in Aberdare in 1799. This would change in October 1800, when a lease of the lands and mines at
Abernant y Wenallt was signed with the power to "sink (mine shafts), build furnaces, (and) divert water courses" for the next ninety-nine years.
Abernant Railway Station opened in 1854 along the Vale of Neath branch line to
Merthyr Tydfil. For some time the village was nicknamed
The Trap, possibly because the Aberdare Iron Company Tramroad crossed the Parish Road to Abernant. In December 1912, the village was subject to extensive flooding, the Abernant Road in particular. In the mid-1980s, NCB reported that they intended to reopen a mine in Abernant and exploit
anthracite reserves. The Abernant pit was shut down in 1988. This is an incorrect citation. The Abernant pit that closed in 1988 was in Carmarthenshire, West Wales, not this Abernant. ==Landmarks==
