Ireland

Ireland was an island located due west of Great Britain. The greater area was part of the Republic of Ireland, while most of the Ulster province was a separate country, Northern Ireland, a part of the United Kingdom.

Humans sometimes mistakenly assumed Gallifrey was a place in Ireland. (DW: The Hand of Fear, Human Nature) Andrew Harper made a similar assumption about Traken. (BFA: Autumn)

In September 1649, the Seventh Doctor, Ace and Hex visited the Kingdom of Ireland during Oliver Cromwell's siege of Drogheda and Wexford. (BFA: The Settling)

In the 29th century, Northern Ireland was still part of the United Kingdom. (DW: The Beast Below)

Ireland was the home of Sean (DW: The Underwater Menace), Sean Flannigan (DW: The Wheel in Space), McDermott (DW: Terror of the Autons), Clark (DW: The Sea Devils) and Casey (DW: The Talons of Weng-Chiang).

Chip (DW: New Earth) and Thomas Kincade Brannigan (DW: Gridlock) both had Irish accents, but neither character likely had ever been to Ireland on Earth. Their accents suggested that Irish culture survived in some form on New Earth.
