St. Eunan's Cathedral or the Cathedral of St. Eunan and St Columba as it is also known, is a Roman Catholic cathedral of the Diocese of Raphoe located in the parish of Conwal and Leck in Letterkenny, County Donegal, Ireland. It was built between the years of 1890 and 1900 and there are two Catholic cathedrals in the county; with an older Roman Catholic cathedral of the same name is located in the town of Raphoe. The Cathedral was commissioned by Cardinal O'Donnell, then Bishop of Raphoe, who in 1888 aged 32 became the youngest bishop in the world at that time. The Cathedral is built in Victorian neo-Gothic style on a site overlooking the town. It was designed by William Hague, the well known Dublin architect and protégé of Pugin, and following Hague's death by his partner T. F. McNamara. It has a spire with a height of 240 feet. White sandstone from Mountcharles was used in the construction. It was shipped along the coast and up the Swilly. Townspeople carried bucketloads of the sandstone to the construction site piece by piece. The cathedral is furnished in oak, with a marble pulpit by Pearse Brothers of Dublin. The pulpit depicts statues of the Four Masters and the Four Evangelists. The stained glass windows that illuminate the sanctuary and the Lady Chapel are by the Mayer firm of Munich. They depict thirteen scenes from our Lord's life. The ceilings are the work of Amici of Rome. The Great Arch illustrates the lives of St. Eunan (better known as St Adhamhnáin) and St. Columba. The sanctuary lamp is made of solid silver and weighs over 1500 ounces. Some sculptures were created by William Pearse who took part in the Easter Rising. There are 12 bells in the Cathedral bell chamber. They carry the names of the saints of Tir Conail - Dallan, Conal and Fiacre, Adomnán, Baithen and Barron, Nelis and Mura, Fionán and Davog, Cartha and Caitríona, Taobhóg, Cróna and Ríanach, Ernan and Asica and Columba. The 12th bell weighs over 2 tons. After the Cathedral was opened the organist played "O'Donnell Abu", "St Patrick's Day", "The Last Rose of Summer", "The Wearing of the Green" and "The Bells of Shandon". In 1985, the Cathedral was renovated and remodeled to better conform to the liturgical requirements of the Second Vatican Council. Care was taken to preserve the style and materials of the original altar in the new altar table and chair. The original altar-piece, an Irish carving of Leonardo's Last Supper, is still present in the Cathedral and has been incorporated into the new altar. The sandstone exterior of the cathedral was cleaned in July 2001. The stone was then repaired and pointed with a special mortar of lime and sand. Krystol Hydrostop was finally applied to the exterior.
