Blackett Level portal is a nineteenth-century entrance structure associated with coal mining operations in Northumberland. The portal marks the opening of an underground level or adit driven into the coalfield, representing the industrial archaeology of the region's extractive industries during the nineteenth century. The structure survives as physical evidence of the mining techniques and infrastructure that characterised coal production in this part of northern England during the period of intensive industrial development.
