Am bron i 300 mlynedd mae de Cymru wedi bod yn ganolbwynt i ddiwydiant tunplat Prydain, gyda melin rolio Pont-y-pŵl yn gatalydd arloesol i weithgynhyrchu tunplat. Yn 1873 sefydlwyd gweithfeydd tunplat Tynewydd ger Cwmbrân. @RC_Archives #DyddMawrthTunplat 1/4
Wedi’i sefydlu ger gorsaf drenau Pontnewydd gan Batchelor and Co (neu Charles Roberts), cafodd Tynewydd sawl perchennog ar hyd y blynyddoedd cyn dod yn rhan o Redbrook Tinplate Co., Sir Fynwy. 2/4 coflein.gov.uk/cy/safle/41548…
Yna fel rhan o Linpac, caeodd y gweithfeydd c.1961 ond mae’n debyg i’w is-gwmni ffatri stampio – Pontnewydd Tin Stamping Co. – i barhau tan c.1966. Mae’r safle bellach wedi’i glirio ac wedi ei ail-ddefnyddio am ddiwydiant ysgafn. 3/4

For almost 300 years, south Wales has been the focal point of the British tinplate industry, with the Pontypool rolling mill an innovative catalyst for tinplate manufacture. Founded in 1874 near Cwmbrân was Tynewydd tinplate works. @RC_Archives #TinplateTuesday 1/4
Founded in 1874 next to Pontnewydd railway station by Batchelor and Co (or Charles Roberts) Tynewydd passed through a number of owners before becoming part of the Redbrook Tinplate Co. of Monmouth. 2/4 coflein.gov.uk/en/site/415481…
Later becoming part of Linpac, the tinplate works closed c.1961 but its subsidiary stamping factory – Pontnewydd Tin Stamping Co. – seems to have carried on until c.1966. The site has been cleared and has been re-used for light industry. 3/4

1/10 Discovery! Abermagwr Roman villa, Ceredigion. Ten years ago this month, initial excavations directed by Dr Jeffrey Davies and Dr Toby Driver confirmed the existence of Ceredigion’s first (and still only) recorded Roman villa, and the most remote villa in Wales.
2/10 Roman villas are not common in Wales; fewer than 40 known or possible villas are recorded, and these are mostly in the south and east of the country. Abermagwr Villa was discovered as a striking cropmark during aerial photography in the exceptional drought of 2006.
3/10 In 2010 funding was obtained for an exploratory excavation in 2010 by Dr Toby Driver and Dr Jeffrey Davies, with loans of equipment from the Dyfed Archaeological Trust. This confirmed what was – and remains – the only recorded Roman villa in Ceredigion (Cardiganshire).
