Cadw lists buildings of special architectural or historic interest in three grades: Grade I for buildings of exceptional interest, Grade II* for particularly important buildings of more than special interest, and Grade II for buildings of special interest. Listing protects the whole building, inside and out.

Every entry on Cadw’s register of listed buildings whose point lies inside the ONS 2022 built-up-area boundary. One list entry can cover a terrace or a group of buildings.

Cadw’s conservation areas via DataMapWales. Hectares are the part of each area inside the built-up area.

The first 1 entry was listed in 1989. 30 came in 1995. Only 0 have been added in the last 15 years.

World Heritage

1 scheduled monument

Two measures, each ranked against every UK town of 1,000 or more, with protected heritage counting twice as much as the age of homes. Protected heritage counts each listed building by its grade (Grade I three points, II* two, II one), each scheduled monument and battlefield two, and each registered park or garden by its grade; it is ranked both per 10,000 residents and as a total, so a village with one fine church doesn’t outrank a historic city. The second measure is the share of homes built before 1919, from the Valuation Office Agency’s council tax records. History is a character grade: it describes the town and isn’t part of the overall grade.

44% of homes are Victorian or older, against 16% across England and Wales. The busiest period since was 1965–72, which added 13% of today’s homes.

Part of Blaenavon Industrial Landscape, a World Heritage Site, lies in Blaenavon. All told, the list holds 31 listed buildings, 3 of them Grade I, including Cast House And Foundry, Blaenavon Ironworks. Its housing is old: 49% of homes date from before 1919, against 15% in the typical UK town. Its Grade I buildings cluster together: 3 of them stand within 400 m of Balance Tower, Blaenavon Ironworks.

Only 30 of the 911 towns nearest its size have more Grade I buildings. A conservation area has protected part of it since 1984. E. E. Clive (1879), Edmund W. Samuel (1857) and Benedict James (1871) are among the 4 people born here before 1900. The rest is about typical: per resident it sits near the middle of UK towns; and it also has a scheduled monument.
