History

Llangenny Paper Mill was founded late C18 and in 1840 became known as the Golden Grove Mill under the ownership of James Jacob & Son, after which it was primarily known for the manufacture of millboards. The first volume of Theophilus Jones' History of Brecknockshire was printed in 1805 on paper from Llangenny Mill. The mill closed c1893 when the company moved its operations to Cardiff. The drying house is shown on the Tithe map of 1839 and may therefore belong to the original mill block. After the sheets of paper had been compressed in posts of sheets separated by woollen felts, they were removed to the drying house and hung in the loft to dry. Drying houses were specialised buildings whose lofts were fitted with adjustable louvres in order to control the air flow, they generally fell into disuse as the 'endless web' of mechanised papermaking, from pulp to finished product superseded the individual handmade sheets. However in the manufacture of millboards layers of paper were fused together and partially dried on heated cylinders, they were then removed to a loft for the drying process to be completed in the traditional way. The remainder of the mill is now ruinous, although mill race and wheelpit for an undershot waterwheel survive.
