NAME                     Thorn Hill/Thornhill  
 
AREA LOCATION   STILLORGAN, entrance to the house is through Cherrygarth Estate on Trees Road, Mount Merrion.   
  
MAP LOCATION    OSI maps of 1838-1845 and 1898-1913 place it in the townland of Stillorgan North and it is annotated as Thorn Hill on both maps and it also appears on 1816 and 1821 maps.

GENERAL An ivy-clad Georgian plain 3-bay mansion, two storey over basement with Ionic portico, the fanlight may be Edwardian but the glass is pure Georgian, secreted away on a substantial site off Trees Road, it was the long-time family home of hotelier PV Doyle and his wife Margaret.  PV Doyle purchased the period house in 1960 when the house stood on 13 acres.  Originally it had two gate lodges - one on the lower Kilmacud Road (close to South Avenue and no longer extant) and one on the old Dublin Road which survives beside Oatlands College along with part of the old entrance avenue, sadly overgrown.   
 
The house has gone though a number of unsympathetic additions in the 1900’s and a lack of maintenance in the 21st century but a substantial amount of the original building survives including the stables.  The house still has its original granite quoins although the façade has been dashed.  Sash windows with original Georgian glass, Portland stone flagstones, curved door joinery and some of the ceilings also seem to be original to the house, as do two fireplaces and some over-door panelling.  Of major architectural significance to the area as the other large houses in Stillorgan North (Beaufield, Oatlands, The Priory and Mount Merrion House) have all been demolished and it is now the sole survivor. 
 
Carysfort maps from 1860 show the house as being bordered on two sides by the Mount Merrion Demesne wall, whether these are the original or have been rebuilt would be pure speculation as the site is now private.  The Land was held by Robert Emmet and then in 1799 was in the possession of Thomas Addis Emmet who leased it to William Fleming for 95 years.  Lease for 50 years from Earl of Carysfort of Glenart Co Wicklow to Thomas Talbot Power of Inverusk, Ballybrack, County Dublin for 50 years, included is 16 acres and two gate lodges.  In 1926 Sir Thomas Talbot Power of the Irish Distillers Group gifts Thornhill House to William Ryan.  1959 see Veronica Ryan running a school from the house.
