Dún Laoghaire

Dún Laoghaire is a suburban coastal town on Dublin's Southside and the administrative centre of Dún Laoghaire–Rathdown County Council, one of the four local authorities in County Dublin. The town grew up around a major harbour built after 1816 legislation; it was called Kingstown from 1821 and took its Irish name in 1920. It became a residential town, a seaside resort and the terminus of Ireland's first railway.

Dún Laoghaire combines a town centre, with one main shopping street (George's Street) and two shopping centres, with one of the largest harbours in the country, known for its two granite piers.

• DLR Lexicon, the central library and cultural centre of Dún Laoghaire–Rathdown, overlooks the harbour beside Moran Park; the modern Pavilion Theatre stands on the former Pavilion Gardens site.
• The People's Park, a Victorian-style park at the eastern end of George's Street, has a playground, bandstand, fountains and tea rooms.
• The National Maritime Museum of Ireland overlooks the harbour.

• Rail: Dún Laoghaire is on the DART, the South Eastern Commuter line and the mainline service from Dublin to Rosslare. Nearby stations at Sandycove and Glasthule and Salthill and Monkstown also serve the area.
• Buses: Dublin Bus and Go-Ahead Ireland routes connect the town with the city centre and the southern suburbs; several terminate near the railway station.
• Airport: an Aircoach service runs between the area and Dublin Airport 24 hours a day.

Dún Laoghaire–Rathdown had the highest standardised average rent for new tenancies of Dublin's four local authorities in Q1 2026, and the Dún Laoghaire local electoral area was above the County Dublin average (see the cost note). Compare listings carefully and check how far a home is from the DART.

The People's Park, with its playground, and Moran Park are in the town centre, the harbour piers and seafront are close by, and DLR Lexicon is the county's central library.
