I made a small version of the Oosterscheldekering (English: Eastern Scheldt storm surge barrier).
It is a part of the Delta Works, which is a series of construction projects in the southwest of the Netherlands
to protect a large area of land around the Rhine-Meuse-Scheldt delta from the sea.
It is one of the Netherlands biggest engineering marvels, that's why it has been declared
as one of the Seven Wonders of the Modern World, so I thought it would be cool
to make a little recreation of it.

If you are unfamiliar with it, here you can behold the IRL version:
