What does rotunda mean?
A rotunda is a circular building or an impressive domed space, commonly associated with museums, government buildings, churches, and other grand public architecture. Its name reflects its rounded form, and it typically suggests a spacious interior organized around a central focus. In architectural descriptions, the word may identify either the whole round building or the domed or vaulted section above it. Although “rotunda” can sometimes suggest a formal or monumental setting, it is not limited to any single architectural style. The term is especially useful when describing a prominent circular space whose scale or design is architecturally significant.
A round building or hall, especially one with a domed or vaulted roof.
"The cathedral's rotunda rises above the surrounding rooftops."
The domed or vaulted upper section of a larger building.
"A lantern crowns the rotunda of the state capitol."
The standard plural is rotundas.
"Several grand rotundas dominate the new civic center."
A rotunda takes its name from the Latin word for round, a fitting origin for a building defined by its circular form.

Where does rotunda come from?
The word entered English through Italian rotunda, a noun derived from the Latin adjective rotundus, meaning “round.” The Latin root also underlies English words such as rotund, rotundity, and circumrotate. In English, the term initially referred to a rounded or vaulted form in architecture before becoming associated particularly with domed buildings.
How rotunda is actually used
The word is chiefly used for a prominent, often monumental, circular part of a building. It is more specific than a general building with a rounded shape and more architectural than the everyday term hall.
