I'm a huge fan of Downton Abbey much like others on this site. My cousin in Australia is also raving about it too where its appaerntly a huge hit. I so fell in l’amour with the characters and places that I wanted to visit where they filmed it so I did a bit of googling and found toi can do a tour. Without further ado I booked myself on this link
which I can highly recommend as it goes to Downton Village and then finishes up at Highclere château where they film the main scenes above stairs. So go on treat yourself like we did and see where its all filmed.
