Lovely film of Wimpole Andrew, we've visited a few times now as our daughter lives in Harpenden so it's quite local, something you always notice on any film is it that it never reflects the true scale of any buildings, it is a very impressive front and back to the hall, you're right in your assumption of the gardens and walled garden looking good in summer, they're stunning. Just a little info for you, the little yellow flower you saw under the tree is Lesser Celandine, but never touch it as it's poisonous if ingested. Looking forward to your Cambridge film, nice city but best to go is when the University are on their holidays 🤣🤣.
