That middle part with the rounded roof.
I believe it's a dome. Also possibly cupola, vault, or rotunda.
It is a dome, but there are many kinds of domes. More specifically it is a cupola. A rotunda is a round building or a round room, so the space under the cupola may be a rotunda, but the cupola itself is not. And I know of no connection to vault.
cupola? rotunda? dome?
Ah thank you.
Have an opinion?
No, basically the thing the statue is on.
I believe it's called a pedestal.
do you mean the dome? that maroon half sphere?
