Long and strange place names are almost a specialty in Ireland and the more unpronounceable the better! 

These ten townlands in Ireland have the country's longest place names on record. With a single word of 20 to 25 letters, the Anglicized versions of these Irish place titles are almost impossible to pronounce.

Glassillaunvealnacurra, Co. Galway

Irish: Glas Oileán Bhéal na Cora. 

This Galway townland way out west translates as “little green island of the mouth of the weir.”

Illaungraffanavrankagh, The Burren, Co. Clare

Irish: To be officially confirmed. 

Although the National Place Names Branch have yet to officially confirm the Irish language version of this place name, it's safe to say that the beginning "Illaun" stems from the Irish word "oileán" meaning "island."

Muckanaghederdauhaulia, Co. Galway

Irish: Muiceanach idir Dhá Sháile

Translates into “ridge shaped like a pig's back between two expanses of briny water” or, more simply, “pig shaped hill between two seas.”

Ballywinterrourkewood, Co. Limerick

Irish: Coill Bhaile Mhuintir Ruairc 

Although the English version may lead you to believe it is a place of eternal snow, the Irish of Ballywinterrourkewood translates as "the wood of the town of the Rourker clan/family."

Corragunnagalliaghdoo Island, Co. Mayo

Irish: Carraigín na gCailleach Dubh

An aquatic bird haven, this townland translates as "The small rock of the cormorants" (a sea-bird).

Carrowkeelanahaglass, Co. Galway

Irish: Ceathrú Chaol an Atha Ghlais

The third Galway town on the list translates roughly into “a narrow green marshland by a stream.”

Cartroncarrowntogher, Co. Roscommon

Irish: To be officially confirmed.

Not to be outdone by their Galway neighbors, the Rossies come in with their own tongue-twisting contribution. 

Knockavanniamountain, Co. Waterford

Irish: Sliabh Chnoc an Bhainne

Translates roughly as “hill of milk” or “Milk Hill Mountain.”

Newtownmoneenluggagh, Co. Kildare

Irish: An Móinín Logach

The only Leinster contribution (the west must like their long-winded place names a lot more), this townland in the county of the Lilywhites translates as "the pitted small bogland."

Scartnadrinymountain, Co. Waterford

Irish: Barr na Scairte

Translates directly into “Top of Dispersal”

Those are some tongue-twisters! Check out this hilarious 2015 sketch from Irish comedy trio Foil Arms and Hog about Irish place names:
