Quadrangular castle

Imagine building a big sandcastle at the beach. Now imagine that instead of using sand, builders used huge blocks of stone to make a castle like this. A quadrangular castle is a type of castle that is made up of four sides or walls that meet at right angles, creating a square or rectangular shape. These walls are usually made of thick stone and are designed to protect the people inside from attackers.

The castle has four corners, where tall towers or turrets are built. These towers provide a good view of the surroundings and are used to watch for any approaching enemies. They were also used to shoot arrows or throw things at any enemy that got too close.

Inside the castle, there is usually a big open space called a courtyard. The courtyard was a very important part of the castle because it was the center of activity, where people would gather for events, training, and even battle. The castle had many different rooms, including a Great Hall, a kitchen, a dungeon, and bedrooms for the lord and his family.

To enter the castle, you would have to cross a moat, which is a deep, wide ditch filled with water. There was usually a drawbridge that could be raised or lowered to let people in and out. This was an important feature because it made it very difficult for enemies to attack the castle.

In summary, a quadrangular castle is a really strong and sturdy sandcastle made of huge blocks of stone that has four walls, tall towers, a courtyard, and a moat with a drawbridge. It was designed to protect people inside from attackers and was used as a home, a meeting place, and a fortress.
