The fifties were quite bleak times in Ireland but things started looking up in the roaring sixties. With this prosperity we saw more taking up the sport and a golf TV series called “Wonderful World of Golf”, commissioned by Shell, featuring Killarney, well and truly put the Club on the map in the US . The course attracted high profile tournaments and even more attention worldwide with special guests like Bing Crosby and Bob Hope playing Killarney.
Swelling numbers led to more land being purchased and the Killeen course was built and opened eventually in 1972.
This ambitious project, which involved the splitting of the Mahony’s Point course in two and extending the course in both directions was met with huge scepticism but this project was driven home by the clear thinking, determined Dr Billy O’Sullivan.
Many feared that a great course would be lost but instead two fine modern courses with distinctive features were born.
In 1991 The Irish Open was held on Killeen with a clinical Nick Faldo emerging as winner over Colin Montgomerie with David Feherty setting a course record of 65 on the closing day. The colourful Payne Stewart was the crowd favourite. Mixed conditions and a tough course earned huge respect from all the professionals. Faldo was one of only three players to finish below par.
In 1992 huge attendances witnessed a dramatic finale with Nick Faldo emerging as winner in a heart stopping play-off with the relatively unknown South African, Wayne Westner. A tired Faldo described the course as a tough, demanding course that is long, narrow and breezy.
In 1996 the Curtis Cup was played on Killeen with the ladies of Great Britain and Ireland beating the USA is a famous victory.
More recently, Killeen has played host to the 2010 and 2011 Irish Open, with England's Ross Fisher and Simon Dyson the respective winners of the tournament.
