Ash Holm alum works is a scheduled ancient monument located near Mulgrave Castle in Yorkshire, representing the industrial heritage of alum extraction and processing in northern England. The site dates from the post-medieval period, when alum production became an important chemical industry supplying the textile and leather trades. The works would have comprised processing structures, storage facilities, and associated infrastructure typical of early modern alum manufacture, which involved the extraction of alum-bearing shale, roasting, and chemical processing. The monument survives as earthwork remains reflecting this significant phase of English industrial development in the vicinity of the medieval castle.
