Where is the largest space frame structure ever built located?

Arohanui, or mine 👍

In architecture and structural engineering, a space frame or space structure (3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports.

I wonder how big the space is at the museum celebrating women who have driven a Ferrari?
