Also on the Trinity College grounds at Dartry is the new (since 1967) home of the centuries-old Trinity College Botanic Garden.
Part of Dartry Road is the boundary between the Dublin Dublin South East and Dublin Dublin South constituencies. This is also the city / county boundary and is physically marked by the River Dodder. The Dropping Well pub at the riverside is built on the site of a mortuary established to deal with dead bodies carried down the river to the pool underneath the nearby waterfall. It was later a well known destination for "bona fide" travellers who had to have gone more than 3 miles to be served a drink during the holy hour when Dublin pubs used to shut between 2.30 and 3.30 in the afternoon. It is now owned by Charlie Chawke.
Dartry Road is known as the scene of the still-controversial killing of IRA member Timothy Coughlin by police informer Sean Harling on the evening of January 28, 1928. It happened opposite 'Woodpark Lodge', where Harling lived at the time.
Its original owner was Obadiah Williams, a wealthy merchant of Huguenot origin. Among later owners was William Martin Murphy, who owned The Irish Independent, was involved with the Dublin United Tramways Company (DUTC) and was a central figure in the dispute known as the "Dublin Lockout" of 1913 where the union side was led by Jim Larkin. The DUTC constructed the tram line from the centre of Dublin to Dartry and Dartry House was built at the original place where the line ended. The terminus of the line and the associated sheds now house an engineering firm.
In 2005, the Mill Hill Missionaries sold the house and the the adjoining at Orwell Park to Eugene Renehan of Walthill Properties for about thirty million pounds. The new owner plans to refurbish Dartry House itself, listed for preservation, and to use the remaining parts of the site for "a low density scheme of apartments and houses aimed at the top end of the market".
