Chain of Office
During their term, An Cathaoirleach wear the official Chain of Office when representing the Council. The chain was created in 1994 and is multiple links of 9ct gold bound to a 9ct gold pendant crest of Dún Laoghaire. The chain has multiple symbols which represent the following:
- Shamrock: This is from the seal of Rathdown no. 1 Rural District Council (harks back to the old Barony of Rathdown).
- Viking ship: The ship represents the Viking associations of this coastal and maritime area, which later came to also represent trade.
- The Irish crown: Pre-independence versions of the crest had a crown representing British imperial connections with the name Kingstown. This was later changed to a more jagged type of crown to reference those thought to be worn by Irish kings such as King Laoghaire.
- Oak branch with acorns: This represents the ancient wooded nature of the entire county and the aspiration for conservation of the natural environment.
- Mountain / hill (the triangle): This represents the hills and part of the Dublin mountains to the south and south-west of the county.
- The Sea: The sea represents the maritime tradition of the County and its importance for trade and recreation. It also represents the common coastline of the two former administrative areas unified by the Council.
