Bridge An ironwork bridge spanning the River Taff constructed in 1793. The name, meaning “bridge of troughs”, comes from its unusual three tier design of a tramroad between two watercourses, one beneath the bridge deck and the other on an upper wooden structure which is no longer present. Pont-y-Cafnau is also designated as a scheduled monument. |

NOTE
The two viaducts constructed as part of the Brecon and Merthyr Railway both straddle the borders of neighbouring historic communities so have separate designations for each of these locations.

In the oldest part of the churchyard below the old church you can see the headstones are plainer, shorter and smaller with the exception of a few more recent stones the headstones are of local stone, limestone, sandstone and Breconshire sandstone known for its beautiful red colour. A small stone of Brecon red sandstone quarried from the edge of Pontsticill with Llandetty marks the grave of Nicholas David of Pontysticill Smith (Smithy) who died 1786 aged 74.
In Vaynor the earliest grave that remains visible today is a beautiful ledger stone marking the grave of the Rev William Watkin Rector at Vaynor Old Church from 1688 until his death in 1704. The Rev Watkin was buried inside of the old church, under the alter. When the church was taken down the stone became open to the elements. It is beautifully carved in relief with the inscription encircling around giving his family lineage.
Ledger stones are inscribed stone slabs usually laid flat into the floor of a church or on the earth to mark the place of burial. There are several ledger stones in Vaynor old Churchyard and quite possibly more as they are easily broken or tend to get covered over, especially when lying flat on the ground. Another ledger stone on the edge of the pathway marks the grave of David Jenkin of Penderyn Parish who died April 1784 aged 78 and his wife Anne died December 1786 aged 81.

The inscription although clear and readable is sited above another faded illegible inscription. The style of the faded inscription appears earlier in date. Was the stone re cut with Thomas’s epitaph? I find it a bit of a mystery. The faded text may have been naturally worn away by the elements however there is no damage to support this in the upper text referring to Thomas. Usually any text at the top of the stone marks the start so the oldest at the top. Whatever is added below therefore comes later. Although you can see the shape of the faded text on the stone but it’s unreadable. I tried ‘grave rubbing’ to get an imprint, but with no luck. I also photographed it from different angles and edited the resolutions to try and improve it with no great success.




Walter J. Lewis (left), born in Salt Lake City, Utah, of Welsh parents, was a missionary in South Wales for the Church of Jesus Christ of Latter Day Saints from 1877 to 1879. He kept a detailed journal of his missionary activities, including meetings attended, church members visited, and letters written and received. But he also includes reference to community and social events and conditions. This is an entry from February 1878, when he was temporarily in Merthyr. The spelling has not been changed from the original.
