Well, technically it's a city. Try to tell any true Canterbarian that we are not a city and they will proudly point at the Cathedral and go "Look. We have a Cathedral. It has spires. There is a choir that sings there. We even have a bloke in a silly hat running the place. This makes us a city"
When you then agree with them that Canterbury is a city (despite its miniscule size) and therefore anyone living there cannot claim to live in the countryside the same Canterbarian will stare at you with pity in their eyes and then patiently turn approximately 180*, point and go "Look. We have fields. Lots and lots of fields. And woods. And Down's. And the air really smells on certain days of the year if you get too close to a recently manured field. We have to wear hunters. We are in the countryside".
In all seriousness though this is why I love this area - benefits of city living, beauty of the countryside and the pleasures of the coast all next to each other. Paris an hour away, London an hour away. Shopping and food and drink and culture and local produce (and local beer and local wine and local cider). This place, nestled in the deep South East of England, with its gory history (murder in the Cathedral. The blood is still there), eclectic culture, quirky cobbles, tea rooms, lopsided shops, bluebell woods and rolling Downs, is just beautiful. I wouldn't be anywhere else.
