Martello tower

A martello tower is a tall building made of stone that looks like a castle. It has thick walls and is used to protect people from danger, like attacks by enemies with weapons.

Imagine a very big sandcastle that you make on the beach. The martello tower is like that, but it is not made of sand. It is made of big stones that are very strong and heavy so no one can knock it down easily.

The tower is built near the sea so that it can look out for any boats or ships that might try to come and attack. There is a staircase inside the tower that goes all the way up to the top, which is like a big room with lots of windows.

People who work in the tower can see very far into the sea from these windows and can use big guns called cannons to shoot at any bad people who try to come near the tower.

Overall, the martello tower is like a strong and safe castle that is used to protect people from danger.
