A former entrance to the Rathfarnham Castle estate in County Dublin. Constructed of granite and taking the form of a triumphal arch, the building’s design according to James Howley (in his 1993 book The Follies and Garden Buildings of Ireland) was inspired by the Porta Portese in Rome: both share a number of features including engaged Doric columns, square recessed panels above niches, and a balustraded top above the arch. One obvious difference is that inside the Rathfarnham entrance can be found a keystone made from Coade stone and representing a hirsute Roman God. When Howley was writing, the architect responsible for this work was unknown, but more recently in his Gazetter to the Gate Lodges of Leinster (2016) J.A.K. Dean has proposed Francis Johnston, the design based on James Wyatt’s entrance to Canterbury Quad, Christ Church College, Oxford: Dean points out that Johnston’s early patron, Richard Robinson, Archbishop of Armagh, was a graduate of Christ Church and had provided the funds for the rebuilding of Canterbury Quad. Alas, despite such a distinguished pedigree, today the Rathfarnham arch languishes neglected on a tiny strip of land, surrounded by housing estates and intermittently subjected to vandalism. It deserves better than this: why might it not be moved into the grounds of Rathfarnham Castle, which would provide a safer home than is the case at present.
