Long range mortar

as i understand there is a long range mortar thing that fires all kind of stuff on your townbell . i read that anvil deals 10% damage to town bell ... so if i understand correctly if a town remains without my protection for few days if i need to work furiosly for example , my town will be destroyed with a mortar and 10 anvils i 1 day ? and question of my life costs 50 pig iron(anvils) and 8 blistersteel(mortar) ?
HOW CAN I PROTECT MY TOWN FROM THIS BARBARITY?
is there some ways to protect yourself or your claim from being bought out with foe townbell after 10 anvil destruction of your townbell?
