French 3D Vauban Fortification Relief Map Exhibit....
The Marquis de Vauban was a 17th century French military leader and the foremost military engineer of his time. His name lives on as defining a style of fortification which used intricate geometry, trenches, advanced redoubts, and interlocking fields of fire. In early 2012, a French history museum staged an exhibition that contained models and dioramas of many of the fortifications that Vauban supervised the construction of or the siege of. A key part of the exhibit was intricate three dimensional models that replicated the fortifications and terrain in exacting detail. The sheer size of some of them has to be seen to be believed.
