The chapelry comprises the western portion of the parish, and abounds with mineral wealth. ..... It is bounded on the north by the river Alyn, which rises in this hilly district.

The new parish of Minera was formed by an Order in Council on 23 May 1844 (gazetted on 6 December 1844) from the townships of Minera and Esclusham Above, which until then had been in the parish of Wrexham.
In 1865, another Order in Council added to Minera that part of the township of Bersham which lay west of Offa's Dyke.
In 1879, a large part of the township of Esclusham Above was transferred from Minera to the new parish of Esclusham.
