Visit The Basilica Di San Marco
Ticked off in October 2016
What it is
St Mark's Basilica is covered with golden Byzantine mosaics.
How to do it
Book a timed entry online. Shoulders and knees must be covered.
Top tip
Climb the Campanile across the square for a view over the city.
My experience
Ticked off, but the full story is still to be written up.
