A Trabuco is a type of medieval siege engine used to hurl projectiles at enemy fortifications. It operates on the principle of leverage, using a long arm to launch stones or other heavy objects over great distances. The design typically includes a counterweight that, when released, swings the arm down to propel the projectile. Trabuco was widely used during the Middle Ages, particularly in Europe and the Middle East. It is similar to other siege weapons like the catapult and trebuchet, but its unique mechanics allowed for greater range and power. These machines played a significant role in warfare before the advent of gunpowder.
