What is "rahoneen"

Rahoneen ("Ráth Eoghainín") is a townland of Ardfert in County Kerry, Ireland. It is notable as the location of an ancient Celtic ringfort; at one time this was known as McKenna's fort, but, after the capture and execution of Roger Casement for treason, sabotage and espionage against the Crown, it became known as Casement's Fort. In the early hours of 21 April 1916, Casement was put ashore at nearby Banna strand from U19.Too weak to travel, he was discovered at McKenna's Fort where he had hidden after arranging delivery of German weapons as part of a plan of arming Irish rebels and creating a rising in 1916 against the British to achieve independence.
