Blackrock (Irish: An Charraig Dhubh) is an affluent suburb of Dublin, Ireland, 3 km (1.9 mi) northwest of Dún Laoghaire.

[7] The Rock Road, which forms the south-western boundary of the park, is said to form part of one of the oldest roads in the country, having been part of the ancient Slíghe Chualann constructed by the High King of Ireland several centuries before Saint Patrick, and which connected Tara with what is now southern County Dublin and north-east County Wicklow.

His son Valentine Lawless, 2nd Baron Cloncurry gave land beside the house for the building of the Roman Catholic Church, St. John the Baptist.

It was the country residence of John Scott, the first Earl of Clonmel, who was chief justice of the King's Bench in 1784.

[11] The Catholic Daughters of Charity of Saint Vincent de Paul founded St. Catherine's Seminary in 1939 with the purchase of the house Dunardagh, Temple Hill.

All of these buildings, except Clareville, are still standing today and form Blackrock College and Willow Park School.

It met in the Blackrock Town Hall until they built St. Andrew's Church on Mount Merrion Avenue in 1899.

[25] The Blackrock Town Hall, Library and Technical Institute is a complex of buildings in Main Street.

This marsh was a cause of local discomfort for years until it was decided by the Blackrock Town Commissioners (established in 1860) to fill the area in and create a park.

The tower became isolated from the sea when the construction of the railway took place, but seawater still flowed into the area at high tide.

"[11] Eddie Heron lived in Sandycove and is known for his achievement as 36 years undefeated Springboard and Highboard Diving Champion of Ireland.

Crean noticed that Ahern was in trouble and together with a young solicitor named Leachman from Dundrum, he managed to bring him ashore.

[32] In 2013, the baths were demolished due to safety concerns following a routine inspection by Dún Laoghaire–Rathdown County Council.

[33] Blackrock covers a large but not precisely defined area, rising from sea level on the coast to 90 metres (300 ft) at White's Cross on the N11 national primary road.

Blackrock has a station on the Dublin Area Rapid Transit (DART) line, which is 15 minutes away by train from the city centre.

The Blackrock bypass was built in the late 1980s and officially opened by Councillor Anne Brady on 24 March 1988.

The bypass is part of the N31 which joins the harbour at Dún Laoghaire to the national Primary Route network.

Blackrock is a major commercial centre, with cafes, restaurants, a wine and beer store, boutiques, hairdressers and barbers, a tattoo and piercing studio, pharmacies, supermarkets, art galleries, antiques and home improvements outlets as well as bars and banks.

In 2016 they launched their first Leprechaun Chase, a hugely popular fun run event for the local community on Saint Patrick's day followed by village entertainment - a Ceilí at the Cross and street performers.

Valentine Lawless (1773–1853) the second Baron Cloncurry, was an Irish politician and landowner that had a summer residence in Blackrock called Maretimo.

[41] James Stephens (1825–1901) at one time lived at 82 George's Avenue, Blackrock and was a founding member of the Irish Republican Brotherhood.

[42] Charles Kickham (1828–1882) lived at James O'Connors former house of 2 Montpelier Place, off Temple Hill.

[42] John Boyd Dunlop (1840–1921) lived in a large 18th-century house called South Hill and developed the first practical pneumatic or inflatable tyre.

[42] Éamon de Valera (1882–1975) lived in a few houses in the area including Bellevue on Cross Avenue 1933–1940.

In his book A Portrait of the Artist as a Young Man he makes reference to the local parish church St. John the Baptist.

He later moved to Dunamase on Cross Avenue and was the Minister for Justice in the Government of The Irish Free State.

He was assassinated on the Booterstown end of Cross Avenue on his way to Mass at his local parish church on 10 July 1927 by members of the IRA.

He was an Irish novelist and satirist, best known for his novels At Swim-Two-Birds and The Third Policeman written under the nom de plume Flann O'Brien.

In 1868, he was nominated first vicar of the newly constituted charge of All Saints, Newtown Park, County Dublin, which he held till his death.

Eoin Dillon, Uilleann piper, of Kila, was brought up in the Blackrock area and lived in Hollypark.
