Rotunda is a city located in Romania. While the name may be associated with various architectural forms, it serves as a specific geographic location within the country.
In a broader architectural context, a rotunda refers to any roofed building featuring a circular ground plan, which is frequently covered by a dome. It can also describe a round room situated within a larger structure. Notable examples include the Pantheon in Rome, which is considered one of the most influential rotundas, and band rotundas, which are circular bandstands typically topped with domes.
