Church of the Immaculate Conception

St Audoen's Church, founded in 1190, is located in Dublin's Old Town. It is the oldest parish church in use in Dublin, a rare example of medieval architecture in Dublin. In 1825 the church building was in a state of ruin, parts of the church were closed or roofless. The architect Thomas Drew was the first to draw serious attention to the architectural and historical importance of the church in 1866. In 1826, the seventeenth-century tower was remodelled by Henry Aaron Baker, but it was not until the major restoration in 1982 that the tower was secured. A Catholic church of the same name is located next door.

Christ Church Cathedral or Dublin Cathedral is an Irish Anglican cathedral. Founded in 1038 by the Vikings who occupied Dublin, it is the oldest of the city's two cathedrals. In 1539, King Henry VIII decided to convert the priory into an Anglican cathedral with a dean and a chapter. The Cathedral was completely renovated during the Victorian era by George Edmund Street. In the twentieth century, further renovations were carried out, particularly between 1980 and 1982.
