Mylnefield souterrains is a pair of Iron Age underground stone-built chambers located in Perthshire, Scotland. These subterranean structures lie approximately 290 metres and 385 metres east of Mylnefield itself, positioned on bedrock of the Arbuthnott-Garvock Group. This geological formation, dating from the Pragian period, comprises sandstone interbedded with conglomerate, siltstone and mudstone, which would have provided suitable material for constructing the souterrains' walls and surrounding stone.
Souterrains of this type were constructed during the Iron Age and served multiple functions within contemporary settlement patterns. Their precise purpose remains debated amongst archaeologists, though evidence suggests they may have functioned as storage facilities, refuges or ritual spaces. The Pragian sandstone and associated rocks at Mylnefield offered practical advantages for their construction, capable of being worked into the stone-lined passages and chambers characteristic of these monuments.
The souterrains at Mylnefield are scheduled monuments, protected by Historic Environment Scotland under reference SM6468. Their survival into the modern period provides valuable insight into Iron Age building techniques and domestic or ceremonial practices across Perthshire. The site's archaeological significance is enhanced by its specific geological setting, which shaped both the construction methods available to Iron Age builders and the conditions affecting long-term preservation of these underground structures.
