Letterson Castle
Letterston Castle is the name traditionally given to a lost medieval fortification in the parish of Letterston, though no standing ruins survive today and even the precise location of its earthworks is uncertain. The name of the village itself derives from Llyfryston or Llyfriston, interpreted by some as “Llŷfr’s farm” and by others as “the place of the fort of Llether,” but later antiquarians assumed this implied a castle site, leading to centuries of speculation. The area lay within the medieval cantref of Pebidiog, under the control of the Bishops of St Davids, and the settlement later became part of the marcher lordship of Haverfordwest. These associations make the existence of a small timber stronghold plausible, as bishopric estates often featured minor defended sites. Several nineteenth century accounts refer to an “old castle mound” or “castle field” in the parish, but none provide a definite description, and no visible motte survives today. It is possible that Letterston once had a timber manorial centre, a moated enclosure, or a small defensible platform controlling the route between Fishguard and Haverfordwest, but agricultural improvement and village expansion during the eighteenth and nineteenth centuries may have levelled any earthworks. Another possibility is that the “castle” was never a full fortification but rather an early manor site, later romanticised by local tradition. Modern archaeological surveys have not identified any clear medieval mound, ditch, or enclosure connected to a castle. The only consistent evidence is the persistent local name and scattered historical references suggesting a lost fortification associated with the early estate centre. What can be said with confidence is that Letterston’s medieval origins and strategic location on an old north–south route make a small Norman or Welsh timber castle entirely plausible, even if now erased. Letterston Castle is therefore best understood as a vanished medieval site, remembered in name and tradition but without surviving earthworks. No physical remains are visible today, and the exact location is unknown. Alternate names: Letterson Castle, Castell Letterston, Llyfriston Fort (traditional association)
