Recorded Monument GA 73:032 (Crannóg) is located on Calla Lake. A crannóg is a (some-times partially) man-made island structure dating from C6th – C17th. The gaelic for tree is crann, and these structures are generally constructed of brushwood, trees and stone.
A visit to the crannóg during Ireland’s big freeze a number of years ago confirmed the presence of a stone structure.
Calla Lake or Lough Acalla is located a few miles from Kilconnell.
