Corrigan's or Emy Mill is located about a half mile to the south of Mullan. This impressive ten storey mill was probably built as a spinning mill originally. This building subscribes to Mc Cullough's statement in relation to the industrial heritage of Ireland: 'Despite the frequent incidence of early industrial buildings in the Irish countryside, they have little place in a cultural consciousness whose healthy, but selective memory, has ordained for us a common agricultural past. Mills, warehouses and barns are often the biggest objects in the landscape, yet they are invisible as monuments through their absence of detail and, paradoxically, through their scale, for which the eye has no reference in the language of formal architecture'. The sheer size of Emy Mill , along with its' regularity of windows and composition of stone with no architectural detail increases its imposing nature and its likeness to a cartesian grid. The main structure of Emy Mill housed a corn mill for many years after the collapse of the linen industry. Then it specialised in hayrakes and coffins for a number of years.
