The map was under the hammer along with an accompanying note at Chorley’s of Cheltenham.
The sketch map was drawn up by Sir Roger Casement while he was in custody at Scotland Yard in 1916.
The ‘Plan of Rath’ suggests that £50 ‘in gold and silver’ along with a lamp and pair of binoculars were buried ‘under some fern bracken and bramble’ in a fairy fort close to Currahane Moat near Ardfert.
It had been wrongly assumed over the past century that the money was stolen by local people.
The accompanying note was written by Frank Hall who was one of Casement’s interrogators and proves that not only did the British secret service know where the money was, but that it had been given to the RIC men who had arrested him, and the binoculars went to the head of Scotland Yard, Basil Thomson.
Although the treasure was recovered the map and note haven’t been seen for 100 years.
The successful bid of £7,000 by Kerry Museum was supported by the Department of Arts, Heritage and the Gaeltacht.
The items will now be put on display at the Kerry Museum and will form an integral part of its ‘Casement in Kerry’ exhibition which is being opened by President Michael D Higgins on the 21st of April.
