Libanus was built in 1841 for the Baptist cause in an isolated position to the west of Llansadwrn in Carmarthenshire. The cause began in 1788 when members of Capel Soar, Llandyfaen (near Llandybie) were baptised at Waunclynda. A movement to erect a chapel for the new group foundered when difficulties were discovered with the proposed site and the group split in to three smaller groups. The first chapel was built around 1790, apparently as a thatched building to serve both Baptists and Methodists in the area. It is said that the two congregations were separated by a wattle screen and the same minister preached to both simultaneously! The chapel at Waunclynda remained a branch of Soar until 1797/8. A minister was appointed to Waunclynda in 1800 and in 1839 the chapel had 80 members. The present chapel was built in 1841 by the chapel members themselves, on land given by one of its deacons, David Price of Blaenwaun. By 1936 membership had been reduced to 17 and the chapel closed in 1998. Following refusal of listed building consent for conversion to a dwelling, it was purchased for a modest sum by Addoldai Cymru in 2003. It was the Trust’s first acquisition.
