Synopsis
At Tantallon Castle in Scotland, a 14th-century stronghold, the need for defense against aggressors shaped its imposing structure. The castle, built with a 12-foot wide curtain wall, withstood early assaults but faced new challenges with the advent of gunpowder. The documentary travels to the citadelle de Bly in France, where military engineer Vauban's innovations are examined, and then to Holland, where modern civil engineering protects against rising sea levels. The film illustrates how engineering adapts to evolving threats.
