The Cathedral Church of the Holy Trinity, or Down Cathedral, is a Church of Ireland cathedral in the city of Downpatrick in County Down, Northern Ireland. It is reputed to be the site of St. Patrick's grave. Parts of the cathedral date to the 13th Century. The building as it now stands was consecrated in 1829. We visited the cathedral and a number of other places in the area while at a conference in nearby Castlewellan. The inset shows St. Patrick's grave. Though not visible in the photo there is a Celtic cross and some of the letters of the name Patrick, on the a stone.
