Calfaria is a Baptist chapel in the village of Penygroes in the community of Llandybie, near Ammanford, Carmarthenshire.
Services at Calfaria were conducted in the Welsh language until recently but are now bilingual.
Calfaria was founded in 1896 by Baptists who worshipped at other chapels in the vicinity and miners who had migrated to the areas to work at the Emlyn and Caerbryn collieries.
The small congregation grew rapidly, and a minister, the Rev Job Herbert, was installed two years before the chapel was built.
Herbert remained minister for forty years.
