Immigrants from Wales in the 12th century, the Barry family quickly began intermarrying with important Irish families of the time. Soon they had huge tracts of land and real wealth. In order to protect their fortune, the clan began building a vast fortification in the 15th century.
Barryscourt Castle survives in remarkably good condition (albeit with a lot of restoration). An authentic 16th-century kitchen and decorative gardens have been recreated.
The castle is just off the N25, 2km east of the turn-off to Cobh and near Carrigtwohill.
