Great Coastal Railway Journeys S02E14 - Carlingford to Dublin

Michael Portillo continues his railway journey along the Atlantic and Irish Sea coasts of Northern Ireland and the Republic of Ireland.

From Newry, he sets off to cross the border into the Republic. On the Carlingford Peninsula, he helps turn and shake 70,000 bags of Pacific oysters. At Newgrange, Michael is blown away by the ancient, acre-sized cairn and his guide's explanation of what happens inside.

Michael visits Dublin Castle, from where Ireland was once ruled by Britain, and meets the grandson of Irish revolutionary Eamon De Valera. At Dublin's docks, he finds out about how investment in the tech sector has transformed the Irish economy.
