An interesting landmark near Brussels city (Belgium 🇧🇪). It’s a building constructed in 1958, with 9 stainless clad spheres connected to form the shape of a unit cell of an iron crystal magnified 165 billion times. It is now a museum with a very nice view point from the top of the building (335ft tall).
Interesting design for sure, and a technical feat by the architects in the 1950s.
