Blaenavon Ironworks: The Fuel Of The Industrial Revolution

Blaenavon Ironworks boasts a wealth of history and is extremely popular with guests staying at the Gliffaes Country House Hotel.

Now one of the finest preserved 18th-century ironworks in the world, the workers’ cottages were featured in the 2007 BBC reality TV series “Coal House” for their authentic look and feel.

Blaenavon Ironworks: A Brief History

Blaenavon Ironworks was strategically located on the southern side of the Brecon Beacons as the hills had a plentiful supply of iron ore, coal and limestone.

The land was leased in 1787 by three businessmen from the Midlands, with construction of the ironworks beginning almost immediately. With the design including the provision of three furnaces, this was the first multi-furnace ironworks to be purpose-built in Wales.

Construction of the ironworks was completed (along with a number of luxury cottages) by 1789, with production beginning the same year. Growth was rapid, and by 1800, South Wales was the largest producer of iron in the world, with Blaenavon Ironworks producing the second-largest amount behind Merthyr Tydfil’s Cyfarthfa Ironworks. By the mid-19th century output and reached an impressive 35,000 tons, but sales then started to decline until its relaunch in 1870.

Now known as Blaenavon Iron & Steel Company, it employed more than 5,000 people but was facing stiff competition from other entrants to the industry. Poor management over the previous half century had left the company on the brink of financial ruin.

Sidney Gilchrist Thomas Experiments

Sidney Gilchrist Thomas was an English inventor. While studying at the Birkbeck Institute, his lecturer claimed “the man who eliminates phosphorus by means of the Bessemer converter will make his fortune”.

In 1875, Sidney believed that he had conceived a way of eliminating phosphorus and disclosed his method with his cousin, Percy Gilchrist, who was a chemist at Blaenavon Iron & Steel Company.

They shared their preliminary results and, suitably impressed by their initial experiments, the manager of Blaenavon Iron & Steel Company allowed Sidney and Percy the use of the facilities to conduct more substantial experiments and also assisted them in securing a patent for their method.

Stack Square Cottages

The construction of the cottages at Stack Square started in 1789 – the same year that Blaenavon Ironworks began production. The cottages were completed by 1792 and housed many of the ironworks’ employees.

Known as Shop Square for the first 60 years, it became known as Stack Square in 1853 when a boiler stack was created in the middle of the square.

The 2007 reality TV show “Coal House” and 2009 follow-up “Coal House At War” featured the cottages in Stack Square, mainly due to their authentic appearance. The cottages have been derelict since 1968 and were equipped to look as they would have in specific years – 1926, 1944, 1953 & 1967.

Featuring original furnishings and decorations and calling on local knowledge from the Blaenavon community, the cottages were transformed into convincing examples of how they would have looked when occupied by the foundry workers.

Overworked And Underpaid: Hard Labour At Blaenavon

Keeping the Blaenavon furnaces fuelled was a thankless job. Labourers worked 12 hours per day, 7 days per week to satisfy the demands of the furnace manager.

You would think that such a physically demanding job would be carried out exclusively by men, but many of the workforce were women and children. At one point, government inspectors discovered nearly 200 children working in various roles within Blaenavon – some who were as young as 5 years old.

Multiple reports suggest that 25% of those children were girls, reinforcing the fact that no-one could escape the pressures of working in one of the United Kingdom’s most demanding furnaces.
