St. Gwendoline's Church stands at the centre of the village of Llyswen as it has done for over 1,000 years. St. Gwendoline is a local Celtic Saint also commemorated in nearby Talgarth church. However today all that remains, apart from the name and the site, is the norman font by the door and the single bell of 1666 in the tower. The rest of the church was totally rebuilt in 1862.
However the church still retains a chalice of 1624 and registers from 1718. Further details of the registers can be found on the Genuki site.
Within the chancel are four stained glass windows given by members of the Christy and Chichester family of Llangoed Hall within Llyswen parish. Llangoed Hall is now a well known country hotel.
