Nethercross is a feudal title of one of the baronies of Ireland. Originally part of the Lordship of Meath, it was then constituted as part of the old county of Dublin. Today, it lies in the modern county of Fingal. The barony was created by Hugh de Lacy, Lord of Meath as his own feudal barony, held directly from himself in capite, and so once constituted a feudal title. His vassals were commonly called "De Lacy's Barons". The barony is named from the cross of the abbey said to have been founded by St. Cainnech in 560 A.D. The cross may today be seen in the old graveyard of the ecclesiastical parish of St Canice in Finglas. The town with the biggest population in the barony is Swords.
Baronies were created after the Norman invasion of Ireland as subdivisions of counties and were used for administration. While baronies continue to be officially defined units, they are no longer used for many administrative purposes. While they have been administratively obsolete since 1898, they continue to be used in land registration, and specification such as in planning permissions. In many cases, a barony corresponds to an earlier Gaelic túath which had submitted to the Crown. In the case of Nethercross, it was probably under the sway of the Danish kings of Dublin immediately prior to the invasion.

Cross
The Nethercross or Lowercross was carved in granite at St Canice's abbey sometime between the 7th and 9th centuries. The original height of the cross is not known as it was dismantled by the clergy during the Cromwellian invasion of Ireland and hidden to prevent its desecration by the Roundheads. In 1806, Rev. Robert Walsh was appointed curate of the Church of Ireland parish of Finglas. Following his literary and antiquarian pursuits, he came to hear the story of the cross. He tracked down an old man whose grandfather, as a boy, had been present at the burial of the cross in a corner of one of the glebe fields. Rev. Walsh unearthed the cross from its hiding place, as described by the old man, and had it erected in the south-east corner of the parish graveyard, where it now stands. Following its recovery. There are spiral designs on the underside of the cross. The cross was the northern boundary marker of the parish from early times at a place which is still called Watery Lanes, north of Mellows Road.
