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.
