Aachen Topographic City Map Display

This is a highly detailed, multi-color topographic display of the city of Aachen (Germany), printed as a large 300 × 300 × 17 mm circular map.
The model is divided into 4 individual quadrants (each 150 × 150 mm) that connect seamlessly using small alignment pins. Once assembled, the pieces form a perfect round representation of Aachen’s urban layout.

The map includes many recognizable landmarks and structures, such as:

• Aachen Cathedral (Dom)
• RWTH Aachen University buildings
• Aachen Hauptbahnhof
• Ponttor
• Lousberg and surrounding elevation features
• Major street networks, parks, and urban green areas

The result is a textured, layered topographic look that stands out beautifully on a wall or shelf.
