Some (to me) interesting facts from Wikipedia about the 11th arrondissement of Paris.
The 11th arrondissement of Paris (XIe arrondissement) is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is referred to as onzième.
The arrondissement, called Popincourt, is situated on the right bank of the River Seine. The arrondissement is one of the most densely populated urban districts of any European city.
In recent years this district has emerged as one of the trendiest regions of Paris.
