Cabinteely () is a suburb of Dublin's southside. It is in Dún Laoghaire–Rathdown, County Dublin, Ireland. Geography Cabinteely lies around the crossroads of Johnstown Road / Brennanstown Road and the Old Bray Road, and on either side of the Stillorgan Dual Carriageway (N11), which is parallel to the Old Bray Road. The R827 road runs from Blackrock and terminates in Cabinteely. Much of Cabinteely is parkland (Cabinteely Park and Kilbogget Park) or open countryside (around Laughanstown and Brennanstown). Cabinteely borders Ballybrack, Carrickmines, Cherrywood, Cornelscourt, Deansgrange, Foxrock, Johnstown, Killiney and Loughlinstown. History and monuments The area has seen human activity since prehistoric times - there is a tomb known as Brennanstown Portal Tomb, Glendruid cromlech/dolmen, or The Druids’ Altar near Cabinteely. Excavations between 1957 and 1999 some 700m southeast of Cabinteely suggest that the area was of "considerable status and importance" from the 6th-7th centuries, with possible evidence of a church, ancillary buildings, possible workshops and a cemetery. Anecdotal evidence suggests that Cabinteely grew up around a tavern () located at a crossroads on the main road linking Dublin with the South. Cabinteely sits at the meeting point of the three medieval civil parishes of Tully, Kill and Killiney, in the half-barony of Rathdown. The ruins of Kill Abbey/Grange Church are near Deansgrange. The modern suburb of Cabinteely is still split between these civil parishes. The ruined 9th century Tully Church and graveyard lies within the modern parish of Cabinteely at Laughanstown. Two high crosses from the 12th century stand in nearby fields, and a wedge tomb, all protected as National Monuments (#216). It is likely the modern Church of Ireland parish of Tullow, with a church nearby in Foxrock, is related to that civil parish of Tully. Similarly, the modern Church of Ireland parish of Kill has a church in Deansgrange. Cabinteely House was built in 1769 for Robert Nugent, Lord Clare, and the surrounding demesne wall still mostly exists today (running along the Old Bray Road, Brennanstown Road, and Cornelscourt Hill). It later passed into the possession of the O'Byrne family of Wicklow, who were prominent in Cabinteely since the 1660s (the family originally lived in Marlfield House). William Richard O'Byrne (1823–1896), MP and author of the Naval Biographical Dictionary, owned and lived in Cabinteely House. Joseph McGrath purchased the house in 1933. Cabinteely House finally passed into the possession of Dún Laoghaire–Rathdown County Council in 1984. Cabinteely was
