Carved Into Stone: The Impossible Fortress of Sisteron - Full Documentary

Описание: Perched on a razor-sharp ridge, the Citadel of Sisteron was engineered to turn sheer rock into an unstoppable weapon. 🏰🪨

Guarding the main gateway into Provence, the Citadel of Sisteron is one of the most astonishing fortresses ever built — a military stronghold fused directly into the rock itself.

Rising on both sides of a steep and narrow ridge, this fortress controlled a natural choke point of titanic proportions, forcing armies, traders, and invaders to pass beneath its walls. What seems like an impossible building site became its greatest strength.

But how did medieval builders transform such extreme terrain into a defensive masterpiece? How were colossal platforms erected on near-vertical slopes? Which ancient foundations did engineers reuse to anchor towers, ramparts, and underground structures into solid stone?

Using original architectural plans, historical records, and cutting-edge 3D CGI, this documentary retraces nearly six centuries of innovation in military engineering — from medieval towers to modernized defenses and a vast underground staircase carved deep into the cliff.

An extraordinary journey into the mind of ancient builders who mastered gravity, terrain, and war to create one of Europe’s most spectacular rock-fortresses.
