A “cupola” is a small, dome-like structure that often crowns a building, typically found on the roof. It can serve various functions, such as providing light and ventilation, or simply enhancing the architectural aesthetics of a structure. Additionally, the term can also refer to a small, vaulted room or a similar architectural feature. In a different context, a cupola can refer to a type of furnace used in metalworking, particularly for melting iron and recycling scrap metal.
