Dyserth is one of the ancient parishes of Flintshire, comprising the townships of Dyserth, Llewerllyd, Rhyd and Trecastell.
The name Dyserth is believed by some scholars to indicate one of the early methods of Christian evangelisation - by hermits; it occurs in several parishes in Wales, and in many parishes in Ireland, as Dysart.
The site of Dyserth Castle stands high on the rocky hill which dominates the village. Now almost nothing remains other than banks and ditch defences of the outer ward. Other evidence survived until the early part of this century, but has since been destroyed by the very extensive quarrying that has taken place in the area.
The Castle was constructed by Henry III following his defeat of Dafydd ap Llywelyn in 1241, and was completed by 1250. It had a very short history, as it was destroyed in 1262 after a siege of some six weeks, by the Welsh, under the leadership of Llywelyn the last.

Church History

Ordnance Survey reference SJ 056794.
The church was mentioned in the Domesday book. It is located in the lower part of the village, near to the famous waterfall. The church has had two different dedications, formerly to St Cwyfan, whose cross stands on the border of the parish with Whitford; and currently to St Bridget (or the Welsh St Ffraid).
The church had become very dilapidated, and was extensively restored/rebuilt by Sir Gilbert Scott betwen 1873 and 1875. The Jesse window at the east end of the church is said to be one of the finest examples of Medieval stained glass in North Wales.
In the churchyard there are a number of very interesting graves, including a group of seventeenth century tomb-chests and table tombs.

The Clwyd FHS website has a photograph of the church.
