Deiniolen is a village in Gwynedd, Wales, at the foot of Elidir Fawr. Deiniolen has views over Caernarfon (7 miles away) and on a clear day, Holyhead Mountain and occasionally the Wicklow Mountains in Ireland, can be seen. The population was 1,909 as of 2011, including nearby Dinorwig.
The slate industry was an important employer in Deiniolen, but since the closure of the quarry in 1969, the economy of the village has been in decline.
Village History 
- Llandinorwig Church
- Llandinorwig church was built in 1857. The money to build the church was donated by the Faenol family. An interesting fact about the church is that the windows are all different.
- Ebenezer Chapel
- Ebenezer Chapel was built in 1823. The first minister was the Rev. David Griffydd. The Rev John Prichard is the minister now. Two of the most important events in Deiniolen are held in the vestry of Ebenezer Chapel. These are the Deiniolen Eisteddfod and the Canival Queen Crowning Concert; local school children take part in both events. The chapel was the source of the village's original name Ebeneser.
- Cefn-Y-Waun Chapel
- Cefn y Waen Capel was built by local quarrymen in 1838. Before the chapel was built the local people held their services either in local farmhouses or in the open air. In 1867 the chapel was worth £2,100 but the chapel also had a debt of £2,100. The first minister was Rev. W. Rowlands.
Deiniolen Silver Band 
The Deiniolen Silver Band was formed in 1835 by a group of quarrymen, and has now grown to be one of Wales' major brass bands. The band is currently competing in the First Section but from January 2009 will be competing in the 2nd Section.
Deiniolen Football Club 
Deiniolen FC was formed around the 1950s when the side was playing in the local Caernarfon & District League. After a year absent from the local league the team has reformed.
