Hope no-one minds me reviving another older thread, but I was wondering if there was one on Lewis-related sites in Oxford and if anyone else here has been there!
I've visited Oxford several times since moving to the UK — it's one of my favourite smaller cities in England, with lots of beautiful architecture and of course fascinating history, as it feels like just about everyone who is anyone was a student or teacher at Oxford or is otherwise associated with the place! (Either that or Cambridge, but for some reason more of my favourite historical figures are connected with Oxford. Well, C.S. Lewis also taught at Cambridge towards the end of his career, but Oxford was his home base for most of his life.)
Anyway, my favourite thing about Oxford in particular is the Lewis connection, and a few years ago I had the privilege of a guided tour of The Kilns like others in this thread have mentioned! It really, really is worth going to if you can get there. Seeing Lewis's own home certainly gave me an even deeper appreciation of his life, the struggles he went through at times, the people he loved and the things that were important to him. It's lovely, too, that the house is still used as a residence for scholars, though I was glad I went during the summer break, as that meant nearly all the rooms were unoccupied and open to visitors.
More information here on the tour — you do need to book in advance, but I contacted them only a few days ahead and they were happy to take me:
