What is recorded here

Rat Isld is a crannog in County Mayo, Ireland. It is a small island where people may have built homes above water, using wood and stone while the lake carried rain and life past them. The name sounds like a place kept separate from ordinary fields, perhaps chosen for privacy, defense or simply the joy of living beside moving water.
