The small medieval village of Church Wilne was located on marginal land in the broad alluvial floodplain of the River Derwent, close to its confluence with the River Trent and several kilometres upstream of the confluence of the Trent with the Rivers Soar and Erewash. All that survives today is the parish church of St Chad’s. This is an isolated building, located some 200m north of the modern river. The church may originally have been enclosed on three sides by a meander of the Derwent, the medieval course of which may be reconstructed from topographic, documentary, cartographic and excavation evidence. The last dwellings in the village were demolished in the 1960s, while the area adjacent to the church was converted after quarrying to a large reservoir (St Chad’s Water) within a water sports centre.
