St Cynwyl's parish church

Historically it was part of the commote of Caeo, which in turn was part of Y Cantref Mawr ("The Great Hundred"), a division of Ystrad Tywi.

It is the location of the Dolaucothi Gold Mines, part of Dolaucothi Estate, whose owner, John Johnes, was murdered by his butler in 1876. The mansion house was demolished in 1952.

The parish church of St Cynwyl in the village of Caeo is a Grade II* listed building.[2]


An electoral ward in the same name exists. This ward stretches south to Llansawel. The total population of the ward at the 2011 Census was 1,613.[3]

The community is bordered by the communities of: Cilycwm; Llanwrda; Llansadwrn; Talley; Llansawel; Pencarreg; and Llanycrwys, all being in Carmarthenshire; and by Llanfair Clydogau and Llanddewi Brefi in Ceredigion.
