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.Tŷ Mawr, a listed 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, which dendrochronological evidence suggests was built around 1490, The house was restored in 1997–1998 and is again being used as a home.
