Description

The monument comprises the remains of several buildings, including a blast furnace, coke oven and leat, and an open excavated area related to the production of iron. Tondu Ironworks was initially a complex of rolling mills, prior to 1853. The works were expanded sometime between 1854 and 1875 to include 23 puddling furnaces and brick stacks, 10 balling furnaces, 4 rolling mill engines and 4 sets of rolling mills, with an associated boiler house of 8 Lancashire boilers and 2 chimneys.

The monument is of national importance for its potential to enhance and illustrate our knowledge and understanding of the development of the iron industry. An ironworks may be part of a larger industrial complex and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
