NOVA · S24E14 — Secrets of Lost Empires: Stonehenge (1)
Synopsis
The stone site is notably characterized by its trilithons: structures formed of two vertical stones supporting a broad, horizontal lintel. This program explores the methods employed to transport and raise these immense blocks, and to precisely position the lintels above. By examining various approaches and adapting ramps, levers, and other tools likely at the disposal of the ancient builders, the team strives to unravel this enduring engineering puzzle.
