Killarney is home to St Mary’s, a beautiful Gothic-style building that serves as the cathedral of the Catholic Diocese of Kerry. Previously, St Brendan’s at Ardfert was the diocese’s cathedral.

English architect Augustus Pugin, who worked on the iconic Palace of Westminster, designed St Mary’s with a rugged exterior and smooth, light-filled interior.

The cathedral was consecrated in 1855 and renovated in the 1970s.
