Beaumont is a northside suburb of Dublin city, Ireland, bordered by Donnycarney, Santry and Artane. It lies within the postal district Dublin 9. Beaumont is also a parish in the Fingal South East deanery of the Roman Catholic Archdiocese of Dublin. The name is derived from the French for "beautiful mount" ( named by Olivia Whitemore and Arthur Guinness in 1764) as the parish is located atop an ascent from Fairview. Its clean air and views across Dublin to the Wicklow mountains inspired the name. From 1764 Olivia Whitmore and Arthur Guinness made their new family home in Beaumont House. The house is a protected structure and can be visited today.
Beaumont was originally a farm in the Civil Parish of Coolock, between the townlands of Kilmore Big and Kilmore Little. It is the former home of the Guinness family from 1764-1855. The original 1764 lease between Charles Gardiner and Arthur Guinness can still be seen in the National Library of Ireland. Guinness took 51 acres (210,000 m2) "more or less situate in the Parish of Coolock" on a lease for the longer of 31 years or three lives, and built a house "at Kilmore" ; it is apparent that he later named the property "Beaumont". His rent was £93 p.a.
RTÉ had a radio transmitter in Thorndale, Beaumont (off Beaumont Road, where Collinswood estate is now), from which from 1982 broadcast RTÉ Radio 2 on 1278 kHz AM to the Dublin region, it ceased broadcasting on December 15, 2003. RTÉ used the Beaumont facility to jam radio signals from pirate radio stations in the 1980s.
