Castlemorris (Welsh: Casmorys; also known as Castle Morris or Castle Maurice) is a small village in the parish and community of Mathry, Pembrokeshire, Wales, south of the Western Cleddau river, on the B4331 road between Mathry and Letterston. It has a population of roughly 150 people.
The Welsh manor (maenor) of Castle Morris lay within the ancient Cantref of Pebediog (later the Hundred of Dewisland).[1] The manor was granted to Maurice FitzGerald, Lord of Lanstephan by his brother David FitzGerald, then the second Norman approved bishop of St David's,[2]
Castle Morris may have acquired its name (Castell Maurice) in the 12th century from Maurice FitzGerald, but it may be a far more ancient relic of the pre-Norman Welsh name - Castell Marlais - Marlais then being the name of the reach of the Western Cleddau river which flows immediately below the village.
In 1302 Sir John Wogan, chancellor of St David's, secured a grant of the manor of Castle Morris for the bishop of St David's.[3]
To the northeast of the village crossroads is the Grade II-listed farmhouse of Pencnwc, a substantial early and late 19th century building that was formerly part of the Bishop of St Davids' estate, leased by Abraham Leach in 1843, and occupied by William Evans.[4] The farm occupies the site of a former timber castle with stone foundations, of which there are no longer any visible remains.
There was a village shop in 1902.[5] From 1906 George Evans was the village smith.[6] In 1910 the village shop, smithy, cottages and 43 acres of land were put up for auction, but bidding only reached £1,900 and the lot was withdrawn.[7] The village had a post office in 1916.[8]
Brian Morris (1930-2001), poet, critic and Professor of Literature, took the title Baron Morris of Castle Morris when made a life peer in 1990.[9]
The building that housed the former shop and post office is now Gwesty Bach, the village pub.
