Cupola

In architecture, a cupola is a relatively small, most often dome-like, tall 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 kupellon) "small cup" (Latin cupa) indicating a vault resembling an upside down cup.[4]

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 chhatri, seen in Indian architecture, fits the definition of a cupola when it is used atop a larger structure.[]

Cupolas often appear as small buildings in their own right. They often serve as a belfry, belvedere, or roof lantern above a main roof. In other cases they may crown a spire, tower, or turret.[3] Barns often have cupolas for ventilation.[5]

The square, dome-like segment of a North American railroad train caboose that contains the second-level or "angel" seats is also called a cupola.[6][7]

Some armored fighting vehicles have cupolas, called commander's cupola, which is a raised dome or cylinder with armored glass to provide 360-degree vision around the vehicle.[8]
