Place & story

A smaller scale of naming

Louth County Council’s Field Names Project records names associated with farming, industry, wildlife, archaeology and relative position. Grouped by townland and civil parish, they preserve a smaller scale of local naming than the county’s principal settlements. [2]

Language needs a local context

The project found particularly strong Irish-language naming in its Omeath material. Its recorded forms, localities and informant information preserve evidence of usage in a district with a distinctive linguistic history. [2]

People & connections

Oliver Plunkett’s Drogheda shrine

St Peter’s Church in Drogheda preserves the shrine of Oliver Plunkett, Archbishop of Armagh, who was executed at Tyburn in 1681. The archdiocese’s account records the later movement of the relic to Drogheda, his canonisation in 1975 and Pope John Paul II’s visit in 1979. This is a continuing religious and commemorative association within County Louth, distinct from Plunkett’s birthplace at Loughcrew in County Meath. [3]

Folklore & tradition

The Cooley landscape of the Táin

The medieval Táin Bó Cúailnge gives the Cooley landscape a central place in the story of Queen Medb’s cattle raid. Dunn’s 1914 translation preserves this literary geography, including the ford at Ardee. [4]
