Twin towers is a sort of building complex that mainly consists of two towers with the same or similar appearances.
His walk across the Twin Towers was much higher at more than 1,312 ft, while his walk across the towers at the Notre Dame Cathedral was at a height of 226 ft.
The sky bridge connecting the two towers has been constructed in such a way that it responds independently to seismic or wind forces, this allows it to retain its own stability, a method that was quite innovative at the time of construction.

The towers were built using a tube design.
