Listed buildings

A 'listed building' is a building, object or structure that has been judged to be of national, historical or architectural interest.

We have 417 listed buildings ranging from for example, Caerphilly Castle which is grade I to the remains of a medieval churchyard cross in the grounds of St. Barrwg's Church, Bedwas which is a grade II.

Listing a building gives it legal protection, so that it can be preserved for future generations to enjoy.

What are the different grades of listing?

Listed buildings are graded to show their relative importance:

  • Grade I buildings are those of exceptional interest
  • Grade II* are particularly important buildings of more than special interest
  • Grade II are of special interest, warranting every effort to preserve them

What are the criteria for listing?

Buildings are assessed against the following criteria:

  • Architectural interest: buildings of importance because of their design, decoration and craftsmanship; also important examples of particular building types and techniques and building of significant plan forms;
  • Historic interest: buildings which illustrate important aspects of the nation's social, economic, cultural or military history;
  • Historic association: close historical association with nationally important people or events of importance in Wales;
  • Group value: especially where buildings comprise an important architectural or historic group or fine example of planning such as squares, terraces or model villages.

In considering whether to list a building, the Welsh Ministers are advised by the Inspectorate of Historical Buildings within Cadw, which makes assessments in the light of these principles. Local authorities and the Royal Commission on the Ancient and Historical Monuments in Wales (RCAHMW) are also consulted.

How is a building listed?

A national survey to identify buildings for listing and to update existing lists was completed by Cadw in December 2005. As a result, approximately 30,000 buildings were listed in Wales.

Listed building consent

You will need the consent from our planning department to demolish a listed building or for any alteration or extension, which would affect its character as a building of architectural or historic interest. The need for listed building consent is different from planning permission but the process is very similar. Visit the listed building consent section for details.
