Sycharth is a motte and bailey castle and town in Llansilin, Powys, Wales. Until 1996 Sycharth was in the historic county of Denbighshire, but was then transferred to the Shire area of Montgomeryshire within Powys. Sycharth Castle was the birthplace of Owain Glyndŵr. Location Sycharth sits in the valley of the river Cynllaith, a tributary of the Afon Tanat. The site of Owain Glyndŵr’s castle lies about a kilometre to the west of the boundary between England and Wales with a belt of woodland on the higher ground to the east known as Parc Sycharth. Immediately to the west of the castle is a farm that was the courthouse for the township until the 19th century. The site is on minor road close to the B4580, south of Llansilin and to the southwest of Oswestry. The site is in the guardianship of Cadw and there is a small carpark with information boards. The earlier history of the castle The castle was situated in the Welsh territory of Powys Fadog which had formed part of the Welsh Kingdom of Powys. Following the Norman Conquest two of the commotes, Cynllaith and Edeyrnion came under the control of the Normans. There seems little doubt that Sycharth or ‘Cynllaith Owain’ was a Motte-and-bailey built by the Normans. An entry in the Domesday Book, would indicate that this had taken place before 1086. The Normans also built a castle at Rhug that would have been the centre for Edeyrnion. These commotes passed into the possession of Madog Crypl c1275-1304, described as Lord of Glyndyfrdwy and Lord of Cynllaith Owain. Madog was a direct descendant of the Princes of Powys and Gruffudd Fychan II, the father of Owain Glyndŵr, was probably his grandson. Owain Glyndŵr inherited Sycharth in 1369 and it was here that Glyndŵr lived with his wife Margaret Hanmer and their children. Iolo Goch's description Iolo Goch described Sycharth as containing ‘nine plated buildings on the scale of eighteen mansions, fair wooden buildings on top of a green hill’ and ‘a tiled roof on every house with frowning forehead, and a chimney from which the smoke would grow; nine symmetrical, identical halls, and nine wardrobes by each one’. Archaeological evidence Excavations in the early 1960s revealed the presence of two timber halls on the flat topped mound, one being 43 metres in length and provided evidence of the site being burned, as it was
