Last week Pascal noticed an old building that seemed abandoned near Bois Colombes train station. According to wikipedia this building was first built at the Champ de Mars train station for the 1878 world fair. For the 1889 world fair the Eiffel tower was build just behind it. And in 1897 the building was moved to Bois Colombes and used as a train station there from 1924 to 1936. It is now abandoned.
