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. Neighbourhood dots: the population-weighted centre of each Census 2021 output area, coloured by its neighbourhood’s (LSOA’s) share of homes built before 1919 (Valuation Office Agency, March 2025).

History Grade
Caerphilly grades C for history
Protected heritage and the age of the town’s homes, against all UK towns.
Protected heritage, for its size and in all (23 points, 7 per 10,000 residents)More than 35% of UK towns
Homes built before 1919 (15%)More than 43% of UK towns
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.
