This oven or hearth at Dark Lane Leintwardine returned a carbon 14 date of AD 10 to 120 (intercept date of 60 AD) and evidence from the environmental samples suggested that it was used for industrial rather than domestic purposes. The date is extremely early for activity associated with Branogenio (believed to be the Roman name for Leintwardine) and indeed the earlier part of the range predates Roman occupation of this area.
