They open into little squares (campielli) - very pretty, and all the bridges too. The wrought iron and windows really draw me, including these little shrines that appear all over the city.
After wandering through the Rialto, we visited the Museo di Storia Nationale (natural history museum, which was beautifully presented. I was really impressed by the dinosaur footprints set under glass in the floor as well as the remains of an 11-metre long ancestor of the crocodile, and a rather gruesome mummy.
The museum is housed in the old Turkish warehouse (Fondaco dei Turchi).
Ruskin campaigned for its restoration in the 1850s and apparently very little is original. I rather liked it, though. Especially this window.
Stopped for lunch near the church of San Polo (son has decided that he likes pizza, provided it's proper Italian pizza), then finally my research team let me buy a chorus pass. The church of Santo Polo (dating to the 9th century) was beautiful, full of bas-reliefs and lots of paintings: very different from a medieval English church (where the paintings tend to be wall-paintings and much paler, and obviously most of the colour comes from the glass - here, it's the shape of the leads that's interesting but no staining, probably because that would interfere with the colours of the paintings inside.
Then to Santa Maria Glorioso dei Frari. Son tiptoed over to tell me that he was blown away by the architecture.
Titian's Assumption is over the altar here and there are also monuments to Canova, and to Titian.
Oh, and another window, because I can't resist it. This is Venetian 'bottle glass' - I guess the nearest to English glass, tinted very pale purple and rose and green and gold. (This doesn't stuff up my book, though - it just stops me making a really, really elementary mistake!)
