Cilanw farm is located approximately half a mile south of Llanboidy. According to heritage consultancy Trysor, 'The recent history of Cilanw Farm can be traced through historic mapping and other sources. It is not known when the holding was established, but by the early 19th century it was certainly one of the holdings of the Maesgwynne Estate, which dominated the local area.'
'The Ordnance Survey's Original Surveyors Drawings (Carmarthen sheet), surveyed in 1819, was the first detailed map series of the whole country. It did not map field boundaries but does differentiate between enclosed and unenclosed land. This map shows that the land around Cilanw farm was enclosed. The farm is marked as "Cellanw," with the farmyard in approximately the same position it is found today. The associated field system is not shown in detail.'
'The first detailed map of the field system of the area is the tithe map for Llangan parish, dating to 1843. This shows that the field system across the holding was already in existence. This field system has survived virtually unchanged to the present day. The tithe map only depicts a single building at the eastern side of the farmyard area, fewer than are shown on the 1819 and 1833 Ordnance Survey maps and should not be considered to be an accurate depiction of the farm buildings.'
'The tithe apportionment, which accompanies the map and was prepared in 1839, records that Cilanw Farm was a 92 acre holding occupied by one William John and owned by Walter Rice Howell Powell of Maesgwynne.'
'The 1889 1:2500 scale Ordnance Survey map shows that the field system on the holding was identical to that shown on the 1843 tithe map. The farmyard complex, named as Cilanau, is shown in detail for the first time by this map. This shows the farmhouse in its present position, with a narrow, linear yard to its eastern side around which a number of small farm buildings were arranged. The 1907 edition of the 1:2500 map shows essentially the same layout of the field system and the farmyard, although the barn to the southwest of the farmhouse appears on this map for the first time. This is also the first map to record the farm name as Cilanw.'
'During the 20th century the farmyard and far building complex developed considerably, with new, larger, agricultural sheds being constructed to the north of the house and original farmyard area. Cilanw is still a working farm.'
In 2015 it was proposed to build a 'single wind turbine with a hub height of 30.5m and 48 metres to the upright blade tip' in a field to the south west of the main complex of buildings at Cilanw farm.
