The West Wycombe Caves are quite local to me, just on the other side of High Wycombe, and a guest felt like seeing them. They have some historical interest.
I went to the Museum of London to see a particular exhibition, and stayed to see the rest of it.
The Geffrye Museum in Hoxton is about to close down for an extended refurbishment, so I went along to it. As usual, the rooms were decorated for a period Christmas.

The Electric Railway Museum is losing its site, and its last open day was last Sunday (8 October 2017). All photos are cc-by-sa as usual.

Also over Easter, I went to the Museum of Science and Industry in Manchester. Images follow: cc-by-sa on everything.
As I was in Manchester over Easter, I visited the IWM North, the only one of the five IWM sites I hadn't been to. It was a bit of a disappointment. Images follow: cc-by-sa on everything.

Since yesterday was the Boxing Day Bank Holiday, I went to the Science Museum for their Cosmonauts exhibition. Images follow: cc-by-sa on everything. (I'd been told photography was prohibited, but there were no signs and nobody tried to stop me. I didn't use flash, which may have helped.)

To Firepower, the Royal Artillery Museum. I hadn't been for eight years, and things had changed a bit. Many photos follow; cc-by-sa on everything.
On a chilly December day, I drove to Greenwich (do not do this, by the way; if you don't have twenty-odd quid in coins or a disposable credit card, just park in Lewisham, it's less hassle) and visited the National Maritime Museum. (Many photos follow; cc-by-sa on everything.)
Yesterday I visited the Didcot Railway Centre for the first time in really quite a few years; probably at least thirty. Lots of images follow: cc-by-sa on everything.
Earlier this month I visited the Swedish Air Force Museum near Linköping, on the site where Carl Cederström (Sweden's first aviator, like so many early flyers a member of the landed gentry with an interest in machinery and little to do) established the first Swedish flying school.
