But nonetheless there has been sightseeing.
I already mentioned Rynek Underground.
The Mehoffer House, which is an artist's house, pehaps more interesting for the interiors than the art, but with an ace cafe, the Meho Cafe.
The National Museum - there are lots of branches, we went to the main building, which seemed mostly arts and crafts + the Lady with the Ermine.
There is probably more to see than we saw at Wawel Hill, but we did the State Rooms and the Royal Private Apartments of the Royal Palace, and the cathedral. Must remark that dwelling in marble halls, or at least spending several hours walking/standing on floors of that substance, does my lower back thing no favours.
We did an organised tour to the Wieliczka Salt Mine: very impressive. (Much more spectacular than the one in Cheshire which is now an archive store.)
Today we went to Kazimierz, which on reflection, was not, being Saturday, the ideal day to do so - had intended going earlier in the week but ran out of time/energy.
There have also been visits to a number of churches, which after a while tend to run together - lotsa baroque.
