In architecture, a cupola /ˈkjuːpələ/ is a small, most often dome-like, structure on top of a building.[1] Often used to provide a lookout or to admit light and air, it usually crowns a larger roof or dome.[2][3]

The word derives, via Italian, from the lower Latin cupula (classical Latin cupella from the Greek κύπελλον kupellon) "small cup" (Latin cupa) indicating a vault resembling an upside down cup.[4]

Cupolas often appear as small buildings in their own right. They often serve as a lantern, belfry, or belvedere above a main roof. In other cases they may crown a tower, spire, or turret.[3] The chhatri, seen in Indian architecture, fits the definition of a cupola when it is used atop a larger structure.

The cupola is a development during the Renaissance of the oculus, an ancient device found in Roman architecture, but being weatherproof was superior for the wetter climates of northern Europe.

The square, dome-like segment of a North American railroad train caboose is also called a cupola. Some armored fighting vehicles have cupolas in the form of a raised dome or cylinder with armored glass to provide 360-degree vision around the vehicle. Barns often have cupolas for ventilation.
