This water mill, described as a corn mill, appears on nineteenth century mapping. The likely medieval origins of this mill site, or one close to it, are revealed in a twelfth century charter. This records a grant of land to Neath Abbey by Maurice de Londres, lord of Ogmore, in about 1140, granted in exchange for land formerly held by Neath Abbey from Richard de Granville.
The boundary of the granted land circumscribes an area in the vicinity of Wick, perhaps the grange of Monknash. But with this gift was added `the site for a mill at the most suitable spot on the waters of the Eweny, the mill to be so constructed that it will not harm my mills by holding back the water.? (1) Two demesne mills of the Ogmore lordship (noted in fourteenth century accounts) lay a short distance downstream towards Ogmore Castle, presumably the lord's mills referred to in the grant not to be harmed by any new construction, and therefore already extant in the twelfth century (NPRNs 414222 & 414237). A mill valued at 100s belonging to the Prior of Ewenny is recorded in an early fifteenth century survey of Ogmore (2).
Ewenny Mill remained in use into the mid-twentieth century. The mill race is shown on early mapping as a diversion of the Ewenny river at a sharp bend some 100m upstream.
