Sligo continued under Gaelic control until the late 16th century when, during the Elizabethan conquest, it was selected as the county town for the newly shired County of Sligo. An order was sent by the Elizabethan Government to Sir Nicholas Malby, Knight, wanting him to establish "apt and safe" places for the keeping of the Assizes & Sessions, with walls of lime & stone, in each county of Connacht, "judging that the aptest place be in Sligo, for the County of Sligo…" The walls were never built.
