Welsh: Eglwys Wythwr
Monington’s Welsh name is Eglwys Wythwr, translating into English as the "church of eight men", reflecting the fact that there were eight freeholders in the parish when it was founded. The origin of the English name is obscure.
Monington is a rural parish in the community of Nevern, close to the source of Nant Ceibwr, the stream that flows through Moylegrove and into Ceibwr Bay. The parish is in the Diocese of St David's and the parish church is dedicated to St Nicholas. The present church, built in 1860, is a Grade II listed building. The Incorporated Church Building Society (later administered by the Historic Churches Preservation Trust) provided funds.
There are 11 other listed buildings or structures in the parish, including several at Pantsaeson in the north of the parish.
Dyfed Archaeological Trust records suggest that a battle took place at Pantsaeson in the early mediæval period.
The earliest-known written records of Monington are from the 13th century when knight's fees were contributing to the manor of Maenclochog. Parishioners of Monington in the 16th century held ancient grazing rights in the Preseli Mountains resulting from an historic association with St Dogmael's Abbey. From 1536 Monington was in the Hundred of Cemais.
An 1838 tithe map of Monington shows named buildings, mills, mill leat, mill pond, gardens (with paths), farmyards, fences, orchard, parkland, woods, quarry (gravel), hill-drawing, footpath and/or bridleway, waterbodies, springs, well and a kiln.
The quarry referred to in the tithe map, Cware Trefigin, was still in operation in 2015 and contains significant deposits of sand and gravel; a sedimentological study was carried out in 2013 as part of a planning application to extend the workings.
