The historic ruins of Monasterboice (Irish: Mainistir Bhuithe) are of an early Christian settlement in County Louth in Ireland, north of Drogheda. It was founded in the late 5th century by Saint Buithe who died around 521, and was an important centre of religion and learning until the founding of nearby Mellifont Abbey in 1142.
The site houses two churches built in the 14th century or later and an earlier round tower, but it is most famous for its 10th century high crosses.
Just west of and clearly visible from the M1 motorway, just north of Drogheda. 5km from Tullyallen, 8km from Drogheda
Access : Sited across a minor road from the carpark. Level but gravel-covered paths around the well-kept site.
