Trecwn (Welsh: Trecŵn [trɛˈkuːn]) is a village in Pembrokeshire, west Wales, 1.6 miles (2.6 km) east of the A40 (Fishguard to Haverfordwest) road in the community of Scleddau.[1]


The history of Trecwn in the 18th and 19th centuries is linked with the Barham family, who funded the building of the school in 1877. Barham Memorial School, a Grade II listed building,[2] closed in 2001 following the closure of the armaments depot (see below) a few years before.[3] Joseph Foster Barham (1759–1832)[4] and his son Charles Henry (1808–1878)[5] were both members of parliament for Stockbridge, Hampshire.

Trecwn was a community in its own right until 2007; however, the population had decreased significantly from 366 to 260 in the years 1980 to 2006, so it was merged into the community of Scleddau.[6]


The church of St Justinian is a Grade II* listed building of mediaeval origin, rebuilt in the 19th century.[7]

Armaments depot[edit]

RNAD Trecwn is a decommissioned 1100-acre (450 ha) Royal Navy Armaments Depot. It was closed in 1995 with the loss of 500 jobs.[8] Omega Pacific in 1998 tentatively proposed the site could be used for storing low-level nuclear waste, a plan shelved owing to public opposition. In 2001 German company EBV suggested using the site for weapons reclamation.[9][10] In 2003 the owners announced that the tenanted homes on the site would be sold on the open market.[8]

Plans submitted by The Valley (Pembrokeshire) Ltd to build a 25-megawatt biomass energy plant on the site were conditionally approved in 2015.[11]
