Saint Patrick’s Cathedral is a unique ecclesiastical building, constructed on a grand European scale with a history stretching back to the early medieval period. The first record of a church on the site dates to the early twelfth century though a number of early medieval grave slabs unearthed in the vicinity may indicate this church was built on the site of an earlier stone or timber building. It became a collegiate church in 1191 and was elevated to the status of a cathedral between 1212 and 1223. Construction of the cathedral was undertaken in the period between 1220 and 1260 and features including the flying buttresses and pointed arch openings are typical of the Gothic style of the time. The survival of medieval masonry, particularly in the choir and Minot’s Tower, add archaeological interest. It has been much modified over its long life including the rebuilding of Minot’s Tower in the early fifteenth century, the addition of its spire in the mid-eighteenth century, the replacement of the roof in the late seventeenth century and restoration work undertaken by R. C. Carpenter c.1845. A large scale restoration programme, undertaken between 1860 and 1865 under the patronage of Sir Benjamin Lee Guinness, is responsible for the cathedral's current appearance. St. Patrick’s Park, which Guinness laid out on an adjacent site, provides an appropriate setting for the cathedral. The worked of skilled masons is evident in both the surviving medieval masonry and the restoration work. The combination of dark calp limestone with the lighter limestone used for the dressings provides colour and textural variety to the exterior. The interior is ornamented with coloured floor tiles, stained glass windows and a number of well-executed monuments and wall tombs which add artistic interest.
