ARMAGH

Overview

Armagh is a historic settlement in Northern Ireland shaped by its religious heritage and astronomical institutions. The settlement is home to two separate cathedrals dedicated to St Patrick alongside the Armagh Observatory, which opened in 1790, and the later Armagh Planetarium.

This page covers the settlement. Its boundaries can differ from those of the local council area.

The Twin Cathedrals of St Patrick

Armagh has two distinct cathedrals dedicated to St Patrick, reflecting the settlement's profound religious history. The Church of Ireland cathedral's history describes Armagh as a monastic centre of learning after Patrick's time. Rather than surviving unchanged, the ancient church endured repeated destruction and rebuilding. During Archbishop O'Scanlon's reconstruction, a crypt was built to allow an eastward extension on the rounded hill. Following damage in the sixteenth and seventeenth centuries and subsequent repairs including re-roofing in the 1660s, the building has seen many later restorations, notably in 1834 and 2004. The twin-spired Roman Catholic cathedral is a separate building whose foundation stone was laid on St Patrick’s Day in 1840. Construction was paused during the Great Famine as funds shifted toward relief, before resuming in 1854 under architect J.J. McCarthy, who continued the project with a changed Gothic design following the death of original architect Thomas Duff. The cathedral was dedicated on 24 August 1873, with interior decoration continuing under Cardinal Michael Logue through mosaic-covered walls and painted ceilings by Oreste Amici, leading eventually to its consecration in 1904.

A Legacy of Science and Learning

Alongside its ecclesiastical heritage, Armagh has a long tradition of scientific inquiry and civic architecture. In the eighteenth century, Archbishop Richard Robinson promoted the city as a centre of building and learning. The Armagh Observatory was intended as the beginning of a university in Armagh, though that university ultimately did not materialise. Designed by architect Francis Johnston, who dated his plans to 1789, the observatory was completed and opened in 1790. Johnston also left his mark on the wider townscape through his work on the courthouse on the Mall and the Shambles Market, and astronomical research has been undertaken at the observatory since the 1790s. Nearly two centuries later, Armagh's scientific story expanded further with the opening of the Armagh Planetarium in 1968 as a separate institution.
