Evoluon
This immense and unusual complex was once a science museum but now serves as a conference centre and was created by the electronics giant Philips.
The sheer magnificence and bizarre nature of the building have transformed it into a tourist landmark and one of Eindhoven’s icons.
The Evoluon building looks like a flying saucer and the dome is 77m in diameter.
While the building now stands as a conference centre, you can still take a tour of its fantastic and futuristic interior.
