History Grade
Machynlleth grades A+ for history
Protected heritage and the age of the town’s homes, against all UK towns.
Protected heritage, for its size and in all (116 points, 537 per 10,000 residents)More than 93% of UK towns
Homes built before 1919 (36%)More than 91% 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.
