The Old Mill was an old, abandoned water-mill. It only appeared in the Redwall TV Series and is not mentioned in the books. This was where Cornflower was held captive when Farlo gave her over to Cluny the Scourge, who tied Cornflower and Farlo's wife Glendel to various parts of the mill's machinery. The water that spins the water-wheel was once connected to the Abbey pond but was cut off by an otter dam, and it appears to be quite large.
