The monument consists of the remains of the Maesteg blast furnaces dating to the 19th century. The original blast furnace was built here in 1837 by the Cambrian Iron and Spelter Company. The blowing engine house was added later in 1839-40. Further furnaces were added in 1841, 1846 and 1850. The ironworks ceased production in 1886.

The monument is of national importance for its potential to enhance and illustrate our knowledge and understanding of the development of the iron industry in Wales. It retains significant archaeological potential, with the strong possibility of the presence of associated archaeological features and deposits. A blast furnace may be part of a larger cluster of industrial monuments 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.
