1. What's in a name?
   The word cupola comes from Latin, through Italian, roughly meaning a small cup.
2. Where have I seen that before?
   Some cupolas resemble upside-down teacups in basic shape. Building domes are considered cupolas, as well. The domes on the Capitol Building in Washington, D.C. and St. Peter's Basilica in Rome are cupolas.
3. What's the point?
   The original function of cupolas was to let light into a building during daylight hours, and to help ventilate the building by convection. Warm air rises, thus drawing in cooler outside air from through doors and windows.
   
   Today we have other means to accomplish both of these, thus cupolas have taken on a more nostalgic and decorative function in architecture.
4. Ye Olde Cupola returns!
   Some architects and builders use cupolas for what they were intended, even in some modern structures. In an effort to conserve energy by using daylight instead of electric lighting, cupolas can provide a measure of help. Likewise, they can still help in providing adequate, comfortable ventilation. In some larger scale projects, large cupolas may be used to contain mechanical or other building equipment.

Tips & Warnings

• Enjoy your cupola; whether it is functional or merely for the nostalgic appeal!
