1124 CE
Dún Bhun na Gaillimhe ('Fort at the Mouth of the Gaillimh') is constructed in 1124, by the King of Connacht Tairrdelbach Ua Conchobair.
The Annals of the Four Masters note that in that year "Three castles were erected by the Connaughtmen, the castle of Dun-Leodhar, the castle of the Gaillimh, and the castle of Cuil-maeile."
This fort is also called a caislean (castle) in the annals.
