The ceremonial county of Lancashire is comprised of twelve local government districts and two unitary authorities: Blackpool, and Blackburn with Darwen.[1]

The seventy Grade I listed buildings in the county are shown in separate lists for each of its component authorities; Rossendale is the only authority in Lancashire with no Grade I listed buildings.[2]

Grade I structures are those considered to be “buildings of exceptional interest”.[3]
