cupola

Ms. Arcenaux said that she remembered looking down at Earth from the cupola window of the SpaceX Crew Dragon spacecraft on the second day of her journey.

It features an 11-foot square cupola with windows on each side, and the tip of that is reachable only by ladder.

On a post office, I saw a strip of asphalt shingles under a cupola that had a copper roof.

The shingles under the cupola looked brand-new.

I knew the copper washing off the cupola roof was protecting the shingles but didn’t know why.
