Lamps provide a golden glow behind the columned niches inside the circular rotunda of the Pantheon. Otherwise, the light comes from the oculus at the peak of the dome.

- Concrete is a construction material composed of cement (commonly Portland cement) as well as other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate such as gravel limestone or granite, plus a fine aggregate such as sand and water) and chemical admixtures. The word concrete comes from the Latin word "concretus", which means "to harden," says Wikipedia.

Concrete solidifies and hardens after mixing with water and placement due to a chemical process known as hydration.The water reacts with the cement, which bonds the other components together, eventually creating a stone-like material. The reactions are highly exothermic and care must be taken that the build-up in heat does not affect the integrity of the structure.

More concrete is used than any other man-made material in the world.

-terrazzo is a faux-marble flooring or countertopping material.
Terrazzo workers create walkways, floors, patios, and panels by exposing marble chips and other fine aggregates on the surface of finished concrete or epoxy-resin. Much of the preliminary work of terrazzo workers is similar to that of cement masons.
