As well as quarrying for limestone and operating lime kilns on the south side of Whiston Road, the iron ore industry at Cogenhoe was also associated with a brickworks west of Roe Farm. There, ‘commons’ and ‘facings’ were made from local clay – the latter bearing the legend, ‘COGENHOE’ in the frog. However, the economic depression of the late 1880s saw the end of both iron ore extraction and brick-making at Cogenhoe. The pond to the west of Roe Farm is the remains of a brick pit.
