"Meliden comprises an extensive tract of rich arable and pasture land, which is in a high state of cultivation: the surface is in general flat, and the whole district, extending to Rhuddlan, is remarkably fertile" [A Topographical Dictionary of Wales, S. Lewis, 1834]
Meliden is one of the ancient parishes of Flintshire. An early recorded reference is in the "Lincoln Taxation" of 1291, but it was also recorded in the Domesday Book of 1086. The parish originally comprised the townships of Meliden, Prestatyn and Nant; but Prestatyn and Nant were lost to the new parish of Prestatyn in 1860.

Some parts of the church fabric are believed to date from the thirteenth century; but the building was extensively restored in 1884. The dedication is to St. Melyd.
The Clwyd FHS website has a photograph of the church.
