Their exhibition is not free, however they have admission free zone.
The architecture is very unique. Even if you are not interested in contemporary art, it is worthwhile. The building is 112.5 metres in diameter with glass wall.
In the middle of the museum, actually it is an admission free zone, there is a swimming pool in which people are walking around. You also can go down to the pool though you need an admission.
