Musée des Plans-Reliefs

The musée des plans-reliefs is like a big toy museum. It has lots of models of cities and forts. But these models are not for playing; they are very special. They are called plans-reliefs. They were made a long time ago by French soldiers. They made them at a time when there were no pictures or maps like we have today.

The plans-reliefs were very important because they helped soldiers see what the cities and forts looked like from up high. They could use the models to plan their battles and attacks.

Nowadays, people visit the musée des plans-reliefs to learn about these models and the history they represent. It's like discovering a secret world from a long time ago. You can see all kinds of places, from mountains to castles to seaside towns. It's like taking a journey through history without even leaving the museum!
