Since the walls of the castle are vertical, and not inclined so that cannon projectiles could bounce off them, the design was meant to repulse conventional siege machinery developed prior to the advent of artillery. Such conventional equipment would have included ladders, siege towers, and battering rams. The overall design of the castle is modest and characteristic of its provincial origin. The rectangular towers are older than the cylindrical ones and there are indications that the technology of the cylindrical towers may have been belatedly introduced to the fortress, given its rural and provincial location.[5]
