La Grande Arche
The building structure of La Grande Arche (Paris, quarter La Défense) reminds us the structure of a ipercube.
From the point of view of topology, it is a torus, which is a sphere with a handle.
In the pavement near the fountain in front of the building we can see parallel lines that seem to converge to a vanishing point.
