Cavern Hole is a comfortable room smaller than the Great hall in and a gathering area for the Abbeydwellers.

Located below the Great Hall, Cavern Hole is accessible through a set of stairs. Cavern Hole can also be reached from the wine Cellar through a small corridor and a sloping ramp. An archway marks the entry between Cavern Hole and the Kitchen.

Not as decorated as the Great Hall, Cavern Hole has large slit windows and a stone floor. It is furnished with a large table and is lit by candles in sconces.

Redwallers usually eat their informal meals, especially breakfast and supper, in this room. It is occasionally used as a meeting place in times of crisis in place of the Great Hall.
