Sligo Church of Ireland Cathedral, designed by the eminent architect, Richard Castle, has an exceptionally interesting history stretching back to the twelfth century as is illustrated by the various re-modellings. The rich stained glass windows add both artistic and historic interest with work by Mayer and Child pointing to a long association with a number of prominent Sligo families including the Pollexfens (W. B. Yeats' mother's family), L'Estranges and Campbells. The graveyard also contains many fine tombs and grave markers. Its grouping with the Catholic Cathedral creates one of the strongest urban set pieces in the town.
