In 1924 Dunguaire Castle was purchased and renovated by Oliver St. John Gogarty. He was a man of exceptional and varied talents, including medicine, athletics, and poetry, and he provided the inspiration for the character Buck Mulligan in James Joyce’s Ulysses. His reputation saw the castle became a venue for many Irish Literary Revival parties, including those attended by Lady Gregory, WB Yeats, George Bernard Shaw and JM Synge.
The restoration begun by Oliver St. John Gogarty was completed by Christobel Lady Amptill in 1954. More recently, the castle was purchased by Shannon Heritage who developed it into a visitor centre, providing a glimpse into the lives of those who lived and worked on the castle from its foundation to today. From April to October, the castle hosts regular banquets and entertainment.
