County Antrim, County Antrim

Origin

Ir. Aontroim ‘single ridge’; earlier OIr. Oentreb ‘single house/habitation’

Background

The county of Antrim derives its name from the county town.  The name also applies to a parish and two baronies.  The original name of Antrim was OIr. Oentreb ‘single house/habitation’ (of which the modern Irish form would be Aontreibh), referring to an early monastery, the site of which is a little to the north of the modern town and is marked by a round tower locally known as The Steeple. The name was later reinterpreted as Aontroim ‘single ridge’ and this is now the accepted Ir. form of the name.
