A listed building in the United Kingdom is a building which has been placed on the Statutory List of Buildings of Special Architectural or Historic Interest and must be a man-made structure that survives close to its original state. It may not be demolished, extended or altered without special permission from the local planning authority. Although named Listed ‘Buildings’, the list also includes other structures such as bridges, monuments, sculptures, war memorials, milestones and mileposts.
In England and Wales, listed buildings are classified in three grades:
- Grade I buildings are of exceptional interest, sometimes considered to be internationally important.
- Grade II buildings are particularly important buildings of more than special interest.
- Grade III buildings are nationally important and of special interest.
Scotland and Northern Ireland also use three grades of classification: A, B and C categories. The assessment criteria differs from the English and Welsh system, therefore listed buildings within these countries do not share the same categorization and are not equivalent.
