Not all Paris churches are made of beautiful stones with golden fixtures and stunning sculptures! Some are simple, yet worth the visit, like Notre Dame du Travail. This amazing church can be found in the 14th arrondissement at 59, rue Vercingétorix. It was constructed around 1900 for the workers who used to build the pavilions for the world exhibition that took place in Paris during this period. It is fascinating indeed, because it looks like a regular Roman church, except that its frame is made of cast iron.
