Star forts from all around the world. These fortifications became the norm after the large-scale introduction of gunpowder weaponry like cannons made castles obsolete. The fort’s design is low to the ground, minimizing it as a target, with walls consisting of stone-clad dirt slopes able to withstand cannon shot. The sharp angles of the structure also partly deflected impacts and helped break up and confound enemy attacks.
