Where to stand, and when

Ferns through history

Ferns was an early monastic centre founded by St Aidan, also known as St Edan, in the early medieval period.

Ferns became the capital of the Kingdom of Leinster, and its most famous king was Diarmait Mac Murchada.

Mac Murchada's appeal for outside military help in the 1160s led to the Norman arrival in Ireland in 1169, changing Irish history.

In tradition, Mac Murchada is said to be buried at Ferns, near the abbey he founded.
