Fort l Ecluse

The Fort l Ecluse is near the village of Collonges, Ain in Eastern France. It instructions the Rhone valley and is a natural front into France from Switzerland between the Vuache hills and the Jura Mountains. The citadel became based by means of a Duke of Savoy and completed by Vauban within the reign of Louis XIV. It turned into destroyed through the Austrians in 1815 but was rebuilt by means of the French and on the identical time appreciably reinforced and heightened. The excessive street intersects a part of this fortification.

In his commentaries at the Gallic War Julius Caesar describes the defile as narrow and tough by using which carts might be scarcely drawn one by one and moreover a completely high mountain overhung it so that very few should without difficulty guard it. In their attempt to migrate to southwestern Gaul in 58 BC, the Helvetia first of all tried to keep away from this direction by using asking Caesar permission to pass the Rhone into Roman territory at Geneva whilst Caesar refused they attempted to pressure their way across at numerous locations best to be rebuffed by a line of fortifications 19 Roman miles long that Caesar had rapidly constructed along the southern bank of the river.
