In architecture, a cupola // is a small, most often dome-like, structure on top of a building. Often used to provide a lookout or to admit light and air, it usually crowns a larger roof or dome.
Cupolas on the towers of Montefiascone Cathedral, Italy.
Cupolas were also used on some old barns for ventilation.
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. 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.
