St. Columb's House, Oratory and national monument in Kells, Ireland

St. Columb's House is a rectangular stone oratory on Church Lane in Kells, built mostly in the 10th century and topped by a very high pointed roof. Inside, a loft holds three separate rooms, and a former upper floor once stood 1.5 m above ground level.

The building was constructed in the 10th century and formed part of the Kells monastery complex. Its creation reflects the monastic building traditions that developed during the early medieval period in Ireland.

The name comes from Columba (Colm Cille), whose relics were brought to Kells in 878 and later moved to Skryne and finally Downpatrick. Monks used the oratory to recite the Liturgy of the Hours, and it may also have served as a shrine church or an abbot's burial place. It once held a large flat stone known as "St Columb's Bed", possibly a grave slab.

The monument sits on Church Lane northwest of Kells Abbey and is easy to reach on foot from the town center. Walking paths in the area connect to other historical sites, allowing you to explore the medieval heritage together.

A large flat stone called "St Columb's Bed", possibly a grave slab, once stood inside the building. The Annals of the Four Masters and a 17th-century survey also record an underground passage linking the house to the nearby church.
