One of a number of gateways providing access to the four-acre walled garden at Barmeath Castle, County Louth. A map dating from the mid-1770s and drawn up by the surveyor Charles Frizell shows this area of the demesne to be a shrubbery with no evidence of enclosure, indicating the walled garden, like so many others, was only created in the late 18th or early 19th centuries. Unusually, all the walls are lined in brick, whereas, as a rule, it was only the south-facing wall that received this treatment since brick retains the heat longer than does stone. The entrances are also distinguished by being given rather grand, pedimented, breakfront gateways. The walled garden here has been restored in recent years and is now open to the public. Readers with no interest in matters horticultural should be warned that the Irish Aesthete is at present curating an exhibition devoted to the history of the Irish country house garden (opening at the Irish Georgian Society’s headquarters, the City Assembly House in Dublin on May 19th) and therefore this subject is likely to feature heavily in the coming weeks.
