Tynewydd Tinplate Works
1874 Tynewydd tinplate works was founded next to Pontnewydd railway station by Batchelor and Co (or Charles Roberts?).
It passed through a number of owners before becoming part of the Redbrook Tinplate Co. of Monmouth.
1904 a subsidiary, the Pontnewydd Tin Stamping Co. opened a tin box factory immediately to the North of the tinplate works and sharing offices, later becoming part of Linpac.
c.1961 The tinplate works closed but the stamping factory seems to have carried on until c.1966.
