Consecrated in 1875, this cathedral, built to designs by George Goldie, is a particularly fine example of the Norman Romanesque revival style, less common than its Gothic counterpart and notable for its clean lines and distinct, well-defined forms. The, relatively sparing, use of well-executed carved detail contributes to a harmoniously balanced whole and the carving itself displays a level of craftsmanship that is of considerable artistic interest. The fine clock is also of note. The building forms a striking group with the Church of Ireland Cathedral and church hall to its east.
