Barnack is historically part of the Soke of Peterborough, which was associated with Northamptonshire but had its own County Council from 1888 until 1974. From 1894 until 1974 there was a Barnack Rural District that was a subdivision of the Soke.
Barnack is notable for its former limestone industry, its Anglo-Saxon parish church and an unusual early Bronze Age burial. As well as Hills and Holes, an old Roman mining site which is now nature reserve.
