Definitely the best place to visit in Winchester by a hell of a lot, and definitely one of the best cathedrals in the country. The history is incomparable and it's a perfect example of cathedral architecture through time, with everything from Romanesque to Perpendicular Gothic, and modern additions. When I visited it was school holidays, a little bit grey but with blue skies later, and not busy at all (I got pictures from one end to the other without any people in, very rare, even at around 11-12ish).

The nave roof is stunning, very similar to that at Norwich, and the west window is like a mosaic of old glass that although isn't perhaps as impressive as others gives off a beautifully clear light and reminds me of the Dean's Eye at Lincoln.

The transepts and the crypt are the oldest parts of the building, in their Norman big-bonedness. The crypt was flooded when I was there which I had been desperately hoping for (although it's probably not the best thing for the cathedral building) - it is amazing. I tried to take a (very cautious) step down from the top step of the main viewing platform and realised I couldn't because the water was only just lower than it - it was very high. But it's beautiful - the statue is reflected perfectly. I'd love to see it unflooded as well and take the crypt tour around to the other side.

The choir is lovely under the crossing, another beautiful ceiling with a helpful mirror to look up. I couldn't see any miserichords but I'm sure there were some - I did find a little finial with a funny looking guy on it who was pretty cool. The roof screen is one of the highlights - every little niche has it's own carved vault, many statues all life sized and with tiny details you can't even make out, and so many other little touches that make it an absolute masterpiece of Mediaeval and Victorian craftsmanship. The area behind is closed off but you can get around into the retrochoir with the tomb of St. Swithin which is lovely and some gorgeous chapels with lovely ceilings. There's a little section of ceiling between the end of the aisles and the retrochoir's first arch where it goes diagonal and the vault becomes really strange and wonky which I adore - a very inelegant solution to a problem that's created a beautiful little detail.

Another highlight was the Kings & Scribes exhibition - it's great to get up into the triforium without a tour. The bottom floor has the Winchester Bible which is very beautiful, the video explaining how they made it is probably not the best for some people (like vegans - it's written on calfskins) but is very interesting. There's a lot of effort put in there. Upstairs you can go inside the library where you can look, on a screen, inside some of the manuscripts, which have some graffiti and other cool little things. There's also a really interesting bit about the mortuary chests where they found the bones of ancient kings, and how they figured out who they are - they're unsure but they've put in a hell of a lot of effort - I watched most of the video on display which was interesting, and loved the interactive screens that went through the science of it. On the top floor there's windows through into the nave aisles' rooves, which are very dark but cool to see, a large balcony over the transept which offers stunning views of the crossing, an exhibition about the building of the cathedral, and another exhibition about the monks' lives which was also good. Loved the bit about the cathedral, and the views too.

The café and shop are also very good - had a lovely panini, good loos. here's also a statue outside the café of the diver who saved the cathedral - very much worth a read, and there's a pub named after him nearby. It's also worth going along the south side because you walk through the buttresses along the wall which makes for great pictures, especially in the golden hour.

So, I highly recommend a visit to Winchester Cathedral. It's simply wonderful. I'll have to come back to take a crypt tour, and the tower tour which I didn't take because I did one at Salisbury.
