Cathedral (Temple McDermot): Building started around 909 by King Flann Sinna and Abbot Colmán mac Ailella. The west doorway has been recently (and somewhat controversially), comprehensively restored with the Gothic-style north doorway, often called the Whispering Arch, dating to the mid-15th century. The Cathedral is the largest of the churches at Clonmacnoise. Rory O'Connor, the last High King of Ireland, was buried near the altar in 1198, joining his father Turlough. Most of the graves currently seen in the church are those of the Coghlan family, whose patriarch extensively rebuilt the cathedral in the mid-seventeenth century.
