The Church of Ireland cathedral was also rebuilt in the eighteenth century. It was a modest building, no bigger than a small parish church, with a tall square clock tower at its west end. An apse was added in the 19th century. The cathedral was used for worship up to 1961. It was badly damaged in a storm on 4 February 1957 and was demolished a few years later, but its partially restored ruins can still be seen.
