Glengad (Irish: Gleann an Ghad, meaning 'valley of the withes')[1] is a Gaeltacht village in the parish of Kilcommon in northwest County Mayo, Ireland.

It is also known as Dooncarton (Irish: Dún Ceartáin, meaning 'Cartan's Fort'),[1] a name which comes from an Iron Age tribal chieftain called Ciortan, a character who appears in the Ulster Cycle legend of the Táin Bó Flidhais.

The village which is largely linear and without a main street, lies to the northwest and northeast of Dooncarton Hill in the parish of Kilcommon in Erris.

Caubeen Mountain (Dooncarton) sweeps down to Broadhaven Bay and Sruwaddacon Estuary and has some of the most spectacular and scenic views to be found in the county if not the entire country.

Glengad is the proposed landfall site for the contentious pipeline from the Corrib gas field, and is the ongoing scene of protests against the project.

When people of Northern Irish/Donegal origin, namely the Coyles, were displaced by the policies of Oliver Cromwell (to hell or to Connaught)in the mid 17th century, they brought with them their craft of making ropes, baskets and creels and they planted willows (from which they obtained their 'gads' or 'sally rods') in this townland where some still remain to this day despite the best efforts of the major landslide in September 2003, to destroy the last vestiges of the willows in the village.

The native Irish people who were sent to 'hell' under Cromwell's policy of 'to hell or to Connacht' were mostly captured and sent as indentured servants to places like Barbados (giving the verb Barbadosed), St. Kitts, and Montserrat in the West Indies to work on British sugar cane plantations, or Virginia and Bermuda (see Irish diaspora).

Prior to the arrival of these displaced people the townland had been known as Dooncarton, a name which it took from the promontory fort known as Dún Chiortáin.

According to the ancient legend, a hero named Fergus came on a plundering raid to Erris which was then owned by the giant Donnell who lived at Glencastle.

During the early 19th century the Irish Tithe Composition Act permitted Protestant clergy to determine fixed payments in order to provide support for them and their families.

Millions of euros of damage were caused, and issues relating to housing, lands and environment will need to be addressed.

Radio and television footage of the region does not appear to have done justice to the widespread damage caused and the effect it has on individuals and on the community.

Immense volumes of peat, soil and stone were washed from the mountain into Sruwaddacon Bay and to a lesser extent into Carrowmore Lake.

Owing to the nature of damage caused, much more mountainside is exposed and therefore the bay is susceptible to receive more deposits as time progresses."
