Connacht incastellated:
pre-Norman and Anglo-Norman
castles west of the Shannon
By Professor Tadhg O’Keeffe

Native pre-Norman kings of Connacht are known to have incastellated their lands from at least the 1120s. A more sustained period of castle-building followed the Anglo-Norman conquest of Connacht in 1235, most of it driven by Anglo-Norman lords from other parts of the Irish colony.  This lecture reviewed the linguistic, historical and archaeological evidence for these processes.
