Limbourne Mill in Wortwell is mentioned in the Domesday Book, and was owned by the Benedictine Nunnery at Bungay. It appears in documents from 1334, 1356 and 1364, and in 1846 it was noted in a history of Suffolk that Limbourne would be unknown were it not for the water mill, which was called Limber Mill at the time. It continued in use until at least 1933, but was unused by 1949. Some of the original machinery survives, and the mill is grade II listed. Homersfield Mill is attested in 1086 and by documents from every century from the fourteenth onwards. The river bank by the weir collapsed in the early 1920s, and was not repaired, resulting in the mill and cottage deteriorating and being demolished in 1927.
