Glasnevin (Irish: Glas Naíon, meaning "stream of the infants", also known as Glas Naedhe, meaning "stream of O'Naeidhe" after an ancient chieftain) is a largely residential middle-class neighborhood of Dublin.
Glasnevin seems to have been founded by Saint Mobhi
(sometimes known as St Berchan) in the sixth (or perhaps fifth) century
as a monastery. His monastery continued to be used for many years
afterwards. St. Colman is recorded as having paid homage to its founder
when he returned from abroad to visit Ireland a century after St Mobhi's death in 544. St. Columba of Iona
is thought to have studied under St. Mobhi, but left Glasnevin
following an outbreak of plague and journeyed north to open the House at
Derry. There is a long street (Iona Road) in Glasnevin named in his
honour. The church on Iona Road is called Saint Columba's.
