Opus africanum is a way of building walls and buildings that has been used for a long time in parts of Africa, especially in ancient times. It involves using small, thin bricks or blocks made out of natural materials like clay, mud or dried animal dung, and arranging them in a certain pattern to make a strong and stable wall.
Imagine playing with building blocks as a kid, but instead of big wooden or plastic pieces, you have tiny, flat and thin pieces made out of different kinds of dirt. These pieces are carefully arranged in a specific way so that they fit together like a puzzle and create a strong and lasting structure.
Opus africanum is a clever way of building that has stood the test of time and is still used in some places today. It also shows that we can use natural and less expensive materials to create important things like homes and buildings.
