The Archbishop's Palace, Armagh, Northern Ireland, is a landmark Neo-Classical building located on 300 acres of parkland just south of the centre of the city.

[4] Richard Robinson was elected Archbishop of Armagh in 1765, which brought with it the Primacy of the Church of Ireland, and was at once dissatisfied with the modest residence provided on English Street, as well as the lack of improvement in the ancient Irish ecclesiastical capital generally.

[2] The house and its walled demesne were referred to by Inglis in 1834 as in excellent order … laid out with much taste...[5]Following the disestablishment of the Church of Ireland in 1871, Archbishop Knox sought to ensure that the palace and its grounds could continue to be used in perpetuity, as they were no longer being able to rely on tithe income for such purposes.

Notable man-made features of the estate include the following: Atop the high-point of the Palace grounds, Knox's hill, stands the Rokeby Obelisk erected in 1782–83, at the southern end of the park.

Both the Northumberland family's and the Royal coat of arms adorn the pedestal, whilst armorial bearings associated with Robinson are detailed on the shaft, as well as his motto, Non Nobis solum sed toti mundo nati.
