Blackrock diabase (cones and dikes) -
RICHARD CROKER (1843-), American politician, was born at Blackrock, Ireland, on the 24th of November 1843.
It was founded by Donnell O'Brien, king of Thomond (1168-1194); and owes its foundation and name to the presentation to his family of a portion of the true Cross, which attracted numerous pilgrims. The shrine of this relic is in the Ursuline convent at Blackrock, Co.
It is the centre of a considerable railway system, including the Great Southern & Western, the Cork, Bandon & South Coast, the Cork & Macroom Direct, the Cork, Blackrock & Passage railways, and the Cork & Muskerry light railway; each of which companies possesses a separate station in the city.
Tivoli (the residence of Sir Walter Raleigh), Fort William, Lota Park, and Blackrock Castle are notable features on the shore; and Passage, Blackrock, Glenbrook and Monkstown are waterside resorts.
