Plymouth Ironworks

Pentrebach Industrial Estate is located on the former site of the Plymouth Ironworks.

Around 1766 Anthony Bacon, founder of Cyfarthfa Ironworks, bought a lease for land owned by the Earl of Plymouth off John Guest and Isaac Wilkinson. Bacon's plan was to build an ironworks that could supply Cyfarthfa with 'pig iron'. Bacon gave his brother-in-law, Richard Hill the job of managing the Plymouth Ironworks.
The Hill family took full control of the works after Bacon's death and by 1806-07, three blast furnaces were in production and 16 puddling furnaces had been erected, enabling Plymouth to produce wrought iron.

Richard died in 1818 and his sons Anthony - who ran the works - and Richard - who dealt with sales - took over.

Anthony was 'the most scientific iron-master of his district' and he made many improvements in the iron making process through experimentation. He was also well respected in the town 'as he had been 'associated with good deeds, with broad and enlightened measures for his peoples comfort...'

Under Anthony the works were extended immensely over the next 20 years and Plymouth's 'bar-iron had a special value and was known for its excellence throughout the world.' In fact the rails they produced were 'A1 rated, and were remarkable for their durability.'

Anthony died in 1862 and the works were sold for £250,000. The works eventually closed in 1880.

Puddlers Bridge

Puddlers Bridge was built to provide a walking and cycling route across the A4060 aa part of the Valleys Cycle Network. The bridge name was chosen by a local Pentrebach resident Mr Alan Lewis who once lived in the former 'The Triangle' terraced housing. The name is dedicated to the highly skilled ironworkers, the Puddlers. These men turned pig iron into wrought iron by heating and stirring molton lumps of metal; they were expert refiners.

The Triangle

The 'Triangle' in Pentrebach was built to house Plymouth's skilled workers, such as Puddlers.

The Triangle was comprised of terraced rows of 2 up, 2 down stone cottages. The houses were arranged in an unusual triangle formation, with a 'village green' in the centre.

The Triangle was demolished on the 12th December 1977.


Pentrebach House

Pentrebach house is the former residence of the ironmaster Anthony Hill. It was built in 1860 and was inhabited by the Hill family for only two years.

Hoover Factory

In 1948 the American company, Hoover, chose Pentrebach as the site of its purpose-built factory to manufacture Hoover Electric Washing Machines. At one point it employed over 5,000 people. In the 1970's it was responsible for the manufacture of the famous Sinclair C5.
