Tower that allows the transmission of messages by signals, thanks to pulleys and ropes, in the form of geometric symbols.
While today a telephone is all you need to communicate with the whole world in a few clicks, the ancestor of the Internet is standing here before you. In its time, the telegraph revolutionized the transmission of messages. It all started with the intelligence of Claude Chappe, who wanted to communicate with friends living a few miles away. This young physicist had the idea, in 1791, to talk to them by signals, with success. With the French Revolution and the wars of the Empire, his system was used to quickly send messages between Paris and the troops without being intercepted by the enemy. The principle consists in sending signals from high places, visible from far away, and relayed approximately every ten kilometers. Pulleys and ropes gave body to the mechanism of articulated arms. The signals sent then take the form of geometric symbols transcribed in a book intended for their interpretation. The Annoux tower was erected in 1809 and served until 1850 before being restored in 1994.
