The Karlskirche (Church of St. Charles Borromeo) in Vienna has scaffolding that was used in restoration work but is now open to visitors. You can take an elevator to a platform at the level of the drum that supports the dome, and then you can walk up steps (if you dare) right up into the cupola on top of the dome. Along the way you can see close-up the dome paintings that you ordinarily would have to view from 150 feet below. When you get to the cupola you find the Holy Spirit, in the form of a dove that looks as if it’s about to sink its claws into you.

The church itself is amazing. It was built in the early 18th century by order of Emperor Charles VI after Vienna had survived a plague epidemic. It’s dedicated to St. Charles Borromeo, who was famous for his work among plague victims in 16th-century Milan.

Is the angel calling a cab, or just waving at someone on the plaza below?
