Up until 31 March 2021, Northamptonshire was divided into seven districts.
The districts of Corby, East Northamptonshire, Kettering, Wellingborough merged to form North Northamptonshire.
The districts of Daventry, Northampton and South Northamptonshire merged to form West Northamptonshire.
As there are 368 Grade II* listed buildings in the county they have been split into separate lists for each former district.
