Castle Caereinion
Castle Caereinion (Welsh: "Castell Caereinion") is a small village and community in Montgomeryshire, Powys, Wales upon the River Banwy (also known as the River Einion), around 8 miles west of Welshpool, and 4 miles east of Llanfair Caereinion. In 2011 the ward had a population of 1810. The community had a population of 592. Castle Caereinion railway station is on the Welshpool and Llanfair Light Railway. The village is named after an ancient castle. The castle was built in 1156 by Madog ap Maredudd. Madog's nephew Owain Cyfeiliog swore allegiance to the English, Owain Gwynedd took the  castle from him and destroyed it in about 1167. It has been suggested that a mound in the churchyard of St Garmon's is the remains of the earthwork castle. This mound is known as Twmpath Garmon, so it could be a preaching mound (as in Llanfechain). The most recent view is that the mound does not appear motte-like and a survey in 2002 failed to find a surrounding ditch. The church of St Garmon was completely rebuilt in 1866 with additions in 1874. Its predecessor was 15th century. Some of the fittings from the earlier church survive, mostly  from the 18th century. St Garmon's was not an important ecclesiastical centre, being classed as a chapel in 1254. Tŷ Mawr, a Grade I timber-framed house, is in Trefnant within the parish of Castle Caereinion, this house represents an important surviving medieval hall house built for gentry of high which, denrochronological evidence suggests was built around 1490, The house was restored in 19971998 and is again being used as a home.
