The British Iron Company was formed in 1824 by the mining engineer John Taylor, along with his associates James Henry Shears, a coppersmith, and a London merchant Robert Small. Several active ironworks were bought during 1825, along with land on which to build further mines, for the smelting, manufacture and selling of iron bars.
Abersychan was one of the principal sites, having obtained a 60-year lease of property there in 1825, and construction began in 1826. From around 1840 iron rails were produced instead of bars and in 1852 the site was sold to the Ebbw Vale Company, remaining active until 1889.
Only the engine-house, manager's house / offices and parts of the six furnaces remain. I visited the site with friends on a late afternoon in February 2008, and with frost on the grass and the moon in a clear sky, it was quite magical. I loved it and it has remained one of my favourite explore since.
