A set of domed glass elevators lifts visitors from the central platform under the arch to the gallery and observation deck on top. The elevator track is detached from the sides of the arch.
Each of the window panels on the outside-facing sides weighs and costs as much as a small car.
The arch is turned at an angle of 6.33° on Paris' main axis, making it a dynamic three-dimensional shape when seen from Paris while still allowing sightlines through the archway. The main reason of this rotation was the congested basement: with a métro station, an RER station, and a motorway all situated directly underneath the building, this angle was the only way to accommodate the structure's giant foundations.
