How strong were castle walls in medieval age? Is there any event in which walls were knocked down by some kind of siege?
Castle walls had varying levels of strength throughout Medieval Europe, as some were made of wood and were quite easy to knock or burn down whilst others were almost impenetrable.
Most sieges during this period were decided by the attackers starving out the defenders and forcing them to surrender due to starvation rather than a direct assault. Some sieges, however, involved the use of siege weapons which were designed to destroy the enemy fortifications.
The most well known of these siege weapons were battering rams, catapults, and trebuchets. Battering rams would use a long wooden pole, sometimes with a metal head, that would be designed to slowly knock down the enemy walls. Catapults and trebuchets were used by flinging large projectiles such as stones at the walls and were often able to breach them over time.
In all, most sieges were decided due to attrition but there are recorded cases of siege weapons being used throughout the Medieval Period.
