Between 1981-1982 I worked at the Banque Nationale de Paris, rue Bergère, Paris.
I worked for a software team in their IT department. Our office was in the attic (grenier) above rue Sainte-Cécile.
To get there we walked over a footbridge (passerelle) that passed between the main building in rue Bergère and ran over the rue Sainte-Cécile.
Here is the front entrance to the Banque Nationale de Paris in rue Bergère.
As you can see, it is a beautiful building.
