Chaumont viaduct

An amazing construction built in the 19 century. The architect was Emile Decomble and it took only 15 months to build this viaduct which is 600 metres long 52 metres high and has 50 arches. There were 2,500 workers and 300 horses and they worked night and day.
Trains still go across the top. Impressive.
I blipped the viaduct last year so thought I'd just blip the arches where Louis and I walked this year!
