Lego Antwerp MOC
2023 - 2025
A custom Lego model of the Antwerp skyline.
A model of the Antwerp skyline built with Lego bricks. Designed together with my brother.
The full instructions are still in progress. It is designed in stud.io and the bricks were ordered from BrickLink.
We integrated these buildings and landmarks:
- Port house
- Hangars
- A crane at eilandje
- A boat
- MAS museum
- Docks
- Red Star Line museum
- London bridge
- Cathedral
- Boerentoren
- Town hall
- Grote Markt with Brabo and some houses
- A tram
- The leien
- Palace of Justice
- "Lichtput" at Opera square
- Central Station
Some buildings, especially the port house, went through a lot of iterations to get the right look.
