A star fort or trace italienne is a fortification in the style that evolved during the age of black powder when cannon came to dominate the battlefield, and was first seen mid-15th century in Italy. Passive ring-shaped (enceinte) fortifications of the medieval era proved vulnerable to damage or destruction by cannonfire, when it could be directed from outside against a perpendicular masonry wall. In contrast, the star fortress was a very flat structure composed of many triangular bastions, specifically designed to cover each other, and a ditch. Further structures such as ravelins, hornworks or cronworks, and detached forts could be added to create a complex symmetrical structure.
