Assessments in Merthyr

The Trust has undertaken numerous assessments, evaluations, excavations and surveys in Merthyr. In the past five years these have included:

  • Extensive excavations at Ffos-y-fran where much of the extractive and water-power management for Dowlais was sited. This work was Runner-up in the Best Archaeological Project Category at the British Archaeological Awards in 2012. Post-excavation work is well-progressed.
  • Excavations at Ynysfach Ironworks (below Merthyr College) where parts of the refining house (where the Crawshay’s developed the so-called ‘Welsh’ process of converting Cast Iron to Wrought Iron) were excavated. 
    • Permanent displays resulting from this work can be seen in the college and a micro-website is hosted by the Trust this includes a walk-through animation designed in collaboration with ThinkIdea which won the Association for Industrial Archaeology Peter Neaverson Award for Digitial Initiative and Innovation in 2014. Post-excavation works are complete but not published
  • Excavations of parts of the Coking Ovens for Cyfarthfa (mostly during the steel making phase, but including parts of the earlier ovens used during iron production). An open day attracted several thousand visitors.

The Trust is currently facilitating a Youth Heritage Forum for Red House Merthyr on behalf of Merthyr Tydfil Housing Association (HLF Supported). They are undertaking several other outreach and engagement activities in Merthyr in the summer and autumn of 2015.
