Following this post I uploaded plenty of photos.
It is a former train station, built at Champ de Mars in 1878 for Paris world fair. It was then moved to Bois-Colombes in 1897 and was given various uses by French railways (SNCF) since (train station from 1924 to 1936, storage area, leisure center).
In 1985, while it was expected to be demolished, it became a protected historical building, but is abandoned since and partially destroyed.
I also finished uploading my London marathon photos!
Now I have to finish uploading Burkina Faso photos from February but there are still a lot of them...
