This is a section of a limestone wall. You can see that it is composed of limestone blocks.

Each block is roughly rectangular but of different sizes, shades and colour.

All of the blocks in different shades and sizes and types go to make the wall.

It takes all of them together to make the wall; if put together well, the wall stands for centuries against all kinds of weather.
