This is the most amazing site, so check it out! Floor plans of Highclere, rooms, corridors, pics of the original building before the Victorian renovation… a great resource. I’m still looking for a coffee table type book that is basically nothing but pics of every room in Highclere and every square inch of the grounds, with a lot of architectural and historical notes. I can’t believe that nothing like this exists, but I sure haven’t found it! 😉 So until it turns up, this page is a great one-stop resource. https://janeaustensworld.wordpress.com/2012/01/29/highclere-castle-floor-plan-the-real-downton-abbey/?fbclid=IwAR00XSdqgzISNd82khLySRgHg8POinzQhN8r8_rE82IEeyZRhYGjHZoSl2w
