Is the Duomo in Florence under scaffolding?

Parts of the dome exterior are being worked on. But the majority of the outside is exposed (albeit dirty, according to my wife who has been there before). Still quite grand though.

The facade of the duomo in Siena IS hidden under scaffolding though, in case that is on your itinerary. The inside is incredible!

Siena is on the itinerary....we will be there in June so they have 2 months to finish clean-up before we get there! The clean-up is worth it though, judging from results at Sistine Chapel in Rome and Notre Dame in Paris.
