Not well know, but well conducted. James Turrell build this space in 2017 in the Kids-Hospital in Zürich. Its main purpose is of course for the kids, staff and family members. To have a space to meditate, think, relax or whatever. Every first Sunday of the month, the public is allowed to visit the place as well. So we did. Every space is so different. Every space is so memorable. I love his work more and more!
