Llidiardau is a small hamlet in Gwynedd, North Wales, approximately 4 miles northwest of Bala, on an unnamed road, 2.3 miles from Arenig Fawr and in the shadow of Mynydd Nodol. The community population taken at the 2011 census was 20.[1]
Llidiardau Chapel was built in 1811 by the Calvinistic Methodists and enlarged in 1831. In 1860 it was rebuilt into its present form, aside from modifications in 1900. It is a Grade II listed building owing to its good state of preservation. Services are no longer held here, and are instead conducted at Talybont chapel, just over a mile and a half away in Rhyd-uchaf.[2]
Llidiardau is within the electoral ward of Llandderfel and the parish of Llanycil.
