CADW responds to Trecynon Iron Bridge now its up to RCTC

I am pleased to inform you that Cadw offered interim scheduled monument consent for this application (subject to various conditions) earlier this month.  We are currently awaiting the applicant’s formal acceptance of the conditions before the consent is finally in place, at which point I understand the applicant will then seek to appoint contractors.

This scheduled monument is a very important and archaeologically significant structure.  Unfortunately, it is in a very poor state of disrepair and I look forward to seeing these repair works completed, and the bridge being re-opened to pedestrians.

The Aberdare Ironworks at Llwydcoed was founded in 1800, when a partnership consisting of John Thompson, John Hodgett, George Scale and John Scale took out a lease for 702 acres of land on the Llwydcoed Forest Estate. The lease was to run for 70 years at the cost of £1,000 per annum. Two furnaces were built on the site which were waterwheel blown, the waterwheel being fed by a leat that was connected to the River Cynon a mile upstream, and the works opened in 1801. The Aberdare Iron Company appears to have started successfully. In 1805 3,586 tons of iron were produced at the works and the company was able to successfully weather the depression in the iron trade of 1813/14 unlike the other Cynon Valley Ironworks.

In 1812 a tramroad was built to connect the Aberdare Ironworks with the Canal Head of the newly constructed Aberdare Canal at Cwmbach. The tramroad crossed the River Cynon twice during its route, once at Gelli Isaf just below the ironworks and again at the Robertstown Tramroad Bridge. In 1819 the Aberdare Iron Company expanded considerably when it bought the nearby Abernant Ironworks. http://webapps.rctcbc.gov.uk/heritagetrail/english/cynon/llwydcoed.html
