Llanymynech may possibly be identified with the Roman township of Mediolanum.
Llanymynech Hill was the main source of limestone for north-west Shropshire and had been described as the Magazine of Limestone for a vast track of country in 1773.
Llanymynech stone for fluxing was exported to ironworks in Coalbrookdale and Staffordshire.
The general area around Llanymynech is one of considerable historical importance, containing a number of monuments of national significance ranging in date from prehistory to the early 20th century.
Llanymynech Hill is occupied by an impressive Iron Age, or possibly Late Bronze Age hillfort, the ramparts enclosing an area of 57ha, making it one of the largest in Britain.
The Llanymynech kiln had 14 chambers, such that at any one time one would be empty, one was being filled, five were pre-heating, two were firing, four were cooling, and one was being emptied.
