Tour de Télégraphe Chappe
The first network of communication, the optical telegraph revolutionised how news travelled in 1794, being the fastest means of transmission ever achieved. In 1850, it can reach 5000 km being relayed by 534 telegraph towers. The only one that remains to this day with its semaphore is in Annoux.
