Described as an English country house, Knole is more like a village - it's massive and has loads of different parts to it. You're only allowed in one section as the others are lived in (by very posh people!) and no photos allowed inside. But it's situated within the most beautiful deer park in Sevenoaks, just outside London.
The day I went was literally the coldest I've been - it even started snowing.. In APRIL!
