D4

Of all Dublin postal districts, Dublin 4 (D4) is probably the most famous outside the city, due in no small part to it being the location of the national broadcaster RTÉ. Its residents are simultaneously stereotyped as wealthy conservatives but also as liberal-minded progressives, as an Irish pastiche of the British 'stiff upper lip' but also as more akin to the American moneyed suburbanite. This is partly due to the large number of fee-paying private secondary schools and Ireland's largest University, University College Dublin being located there. Many of these institutions are famed for the popularity in rugby - considered a mainly upper-middle class sport. Many foreign embassies are located in D4, due to the prevelance of large Georgian, Edwardian and Victorian buildings.

D4 pronunciation renders words such as 'alright' as 'awlrite', 'car' as 'core' and 'phone' as 'phewn'.

The book The Orange Mocha-Chip Frappuccino Years features the character Ross O'Carroll Kelly (note the double barrelled surname, which is considered pretentious) who embodies the D4 stereotype. The entire book is written phoenetically in the stereotypical D4 style.
