In order to investigate the possible forms the roof may have taken, NOVA's team constructs models at a smaller arena in Spain.

Pharaohs who built magnificent temples to preserve their names for eternity often graced temple gates with pairs of obelisks, four-sided shafts of granite that taper gently upward until the sides meet at the top to form a pyramid shape. NOVA's team of experts attempts to build, transport, and raise a scale model obelisk using those materials available to ancient Egyptian engineers: rope, dirt, sticks, and stones.

Even without such technological advances as wheels, arches, draft animals, iron tools, or a system of writing, the Inca—utilizing a tradition of shared labor—achieved a number of engineering feats.

A distinctive feature of this stone site are the trilithons, which consist of two upright stones topped by a horizontal lintel stone. In this program, the NOVA team considers how to transport and raise the massive stones, as well as how to place the lintel stone on top. By comparing different strategies and adapting ramps, levers, and other tools that might have been available to the ancient builders, the team works to meet the challenge.
