Cilgwyn Chapel has roots in one of the oldest nonconformist congregations in Wales.  Early Presbyterians were meeting at nearby Cilgwyn Isaf farm as early as 1654. They built their first chapel at Cilgwyn Uchaf in 1689. From 1709 until 1760 were under the leadership of the Rev. Phylip Pugh, Blaenpennal, a Presbyterian minister who influenced the young Daniel Rowlands, Llangeitho.  In 1840, Cilgwyn chapel was moved stone by stone to its present site in Llangybi. By the 1950s the chapel was out of use and fell into dereliction. It was saved during the 1980s when members of the local community turned it into a hall for the use of young people of the Urdd Gobaith Cymru. It is today used by the village school. Trysor 2011.
