Historically, those were the best walls money could buy. And they were practically indestructible in the ancient era, as long as they were adequately defended. If walls that strong were easy to knock down with stone-throwing catapults, the even more expensive cannon would never have been invented!

You should, historically speaking, consider yourself very lucky indeed if you manage to breach large stone walls at all.
Chartage's in 150- 148 BC would probably have qualified, took the Romans two years of siege to breach/storm them and take the city.
