St Eugene's Cathedral is the Roman Catholic cathedral located in Londonderry, Northern Ireland. Fundraising for the building of the cathedral took place from 1840. Work began on the construction of the cathedral in 1849.
Money was raised not just in Derry and Ireland, but also in America where around £4,000 was raised. The architect commissioned to design the cathedral was James Joseph McCarthy who had already built numerous cathedrals across Ireland. The plan of the cathedral is a simple neo-Gothic expression.
The cathedral was officially opened on 4 May 1873 by the then Bishop of Derry, Francis Kelly. The project to build the cathedral's bell tower and spire was postponed, as no funds were available for the project. At first the cathedral's windows were made of plain glass due to lack of funds. It was not until the late 1890s when stained glass windows were installed. Work on the bell tower and spire began on 13 August 1900, with the building contract awarded to Courtney and Co from Belfast. Work was completed on 19 June 1903.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
