These furnace bases are some of the few remains left of the ironmasters district.
There is a disagreement between the notice board on site and a Cleveland Industrial Archaeology Report from 1979.
The CIAS report states Bernhard Samuelson built five furnaces known as the “old side” 1864 – 1867 and three more known as the “new side” in 1869 -1871. The notice board says the remains are the three ‘new side’ blast furnaces built in 1874.
The ironstone used here was mined in the Slapewath / Spa Wood area.
