Counterscarp

A counterscarp is like a big wall that protects a castle or fort. Imagine you are playing a game of hide and seek with your friends and you build a big wall out of pillows to hide behind. The wall you built is like the counterscarp because it's a barrier between you and your friends.

The counterscarp is usually built on the outside of a castle's walls, and it's designed to make it more difficult for the enemies to climb over and attack the castle. It can also be used to trap enemies who manage to climb over the main castle wall.

The counterscarp can be made out of different materials like stone, brick, or earth. It's important because it helps protect the people inside the castle and keeps them safe from harm. So, think of the counterscarp like a strong and protective shield that keeps everyone inside the castle safe from harm.
