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.

1 registered park or garden

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.

20% of homes are Victorian or older, against 16% across England and Wales. The busiest period since was 1973–82, which added 23% of today’s homes.

Valuation Office Agency, council tax stock of properties by build period, 31 March 2025, for the neighbourhoods (LSOAs) that make up the town, split by where their residents live. Homes with no recorded build period (0 here) are left out; 1939–44 is not a period in the data.

More of Rossett’s homes are old than in most places: 22% were built before 1919, against 15% in the typical UK town. All told, the list holds 9 listed buildings. A conservation area has protected part of it since 2011. The rest is about typical: like most towns its size, it has no Grade I building; per resident it sits near the middle of UK towns; and Arthur Griffith-Boscawen (1865) and John Trevor (1563) were born here before 1900.
