. Chapter IX of Weston St John Joyce's The Neighbourhood of Dublin
(third and enlarged edition, 1920, courtesy of Ken Finlay's wonderful http://www.chaptersofdublin.com
), situates the house thus: "We first proceed to Enniskerry by the Scalp, continuing straight ahead at the upper end of the village street, passing on the left the church, the spire of which is such a conspicuous feature in pictures of Enniskerry, and on the right, one of the entrance gates to Powerscourt Demesne. As we turn the corner just opposite the entrance to the Dargle, we descend a very steep decline down to the bed of the Dargle River - a very dangerous descent in the old cycling days before the invention of rim brakes. At the bottom of the hill is the entrance to Powerscourt known as the Golden Gate, with its pretty lodge, and beside it, Tinnehinch Bridge over the Dargle. Near the bridge, and situated in the sheltered vale of the river, is Tinnehinch, for some time the residence of the distinguished patriot and statesman, Henry Grattan, who spent his declining years in the seclusion of this romantic retreat. Twiss in his Tour Through Ireland
(1775), states that this house was designed and erected by the then Lord Powerscourt as an inn, and that it was for some years the leading hostelry in this district, and Arthur Young spent some days there, as stated in the quotation further on, during his tour in Ireland in 1776."
On 4 November 1999, in a property feature article, The Irish Times
reported that "A Co Wicklow ruin that was once the home of Irish patriot Henry Grattan is expected to make over Â£1 million at a Jackson-Stops auction on December 1st. Tinnehinch, in Enniskerry, was demolished without permission in the 1950s by an English property developer, David Harris, who sold off its fixtures at an open-air auction." The Irish Independent
also covered the sale on 20 November http://www.independent.ie/unsorted/property/charming-old-ruin-391143.html
, confirming the Harris details. On 12 December, The Irish Times
reported that "Ruins of Grattan house sell for about Â£2 million. In Co Wicklow, the ruins of a house that was once the home of Henry Grattan, along with several cottages at Tinnehinch, in Enniskerry, Co Wicklow, was withdrawn at Â£1.8 million and sold later for a price thought to be close to Â£2 million through Jackson-Stops."
