A trace italienne or bastion fort denotes a style of fortification that evolved during the early modern period of gunpowder. The design of bastion forts as a pentagon or hexagon and with bastions at the corners of the wall eliminated so-called blind spots or dead zones (as were common to ring-shaped fortifications) and allowed fire on attackers from protected positions. The trace italienne was a response to the increasing threat of cannons dominating the battlefield in the mid-15th century.
