Clynderwen (; ) is a rural linear village and community, historically in Carmarthenshire in Wales, but administered as part of Pembrokeshire. It lies on the A478 Tenby to Cardigan road south of the village of Llandissilio and north of the town of Narberth. The village has its own community council of 10 members. Name Clynderwen, translating into English as "oak thicket", is named after an estate of the same name. On 1 April 2003, the village was transferred from the administrative county of Carmarthenshire to that of Pembrokeshire, following a boundary change between the counties. The name of the community council is officially spelt Clunderwen. History The earliest known record of Clynderwen is in 1822: a mansion and farm of that name, the Clynderwen Estate, is to the east of the present village and may have dated back to the 17th century. Robert Frederick Gower, High Sheriff of Pembrokeshire in 1844, whose son Erasmus Gower rose to the rank of admiral, owned Clyn Derwen (sic). Clynderwen was listed in The Welsh Church Year Book of 1929 as having a Chapel of Ease in the parish of Llanfallteg with Clynderwen with Castell Dwyran and had been listed in the parish of Castell Dwyran since before 1850. The village developed after the advent of the railway in 1854. The Great Western Railway (West Wales Line) to London from the ports of Milford Haven and Fishguard passes through the village at Clunderwen railway station. From 1876 a light railway, the Narberth Road and Maenclochog Railway ran from Clynderwen to Rosebush slate quarries via Maenclochog. The line was closed to passengers in 1937 and to freight in 1949. The railway encouraged the development of the local economies and Clynderwen became a focus for agricultural produce and livestock shipment. Clynderwen and Cardiganshire Farmers cooperative opened its first branch in the village in 1904, the first of 22 covering much of Wales. The cooperative was a prime mover in a number of agricultural advances and projects beneficial to the farming community particularly during the depression in the 1920s and the technical revolutions after World War 2. The Clynderwen Agricultural Society was established in 1911 and held an annual show until 1963 and from 1979 to the present. The Clynderwen Young Farmers Club, established 1929, was the first in Wales. The village was notable for the efforts of the James brothers who in 1913 were the first
