The '''Chappe signal towers''' were a system of semaphore relay stations for long distance communication.

Invented by [[Claude Chappe]] in 1792, the relay line consisted of towers spaced between 12 and 25 kilometers apart, each fitted with a telescope. The wooden arms of the towers would form codes which got transmitted along the system, making it possible to quickly transmit crucial information.<ref name="Chappe DB">''[[Assassin's Creed: Unity]]'' – [[Database: Chappe Signal Towers]]</ref>

When [[Austria]]n forces under the [[Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel|Duke of Brunswick]] marched on Paris, royalists planned to signal the vulnerability of the city defenses to them through the signal towers. [[Thomas-Alexandre Dumas]] had [[Parisian Brotherhood of Assassins|Parisian Assassin]] [[Arno Dorian]] sabotage four of the towers to cut off the royalists' communication with the Duke.<ref name="Nice Chappe">''Assassin's Creed: Unity'' – [[A Nice Chappe]]</ref> Arno had another encounter with the Chappe towers when solving a [[Nostradamus Enigmas|riddle]] from [[Nostradamus]].<ref name="Nostradamus">''Assassin's Creed: Unity'' – [[Taurus]]</ref>

Thanks to the signal towers, on September 1, 1794, [[Paris]]ians were informed of the capture of Conde-sur-L'Escaut from the Austrians, 220 kilometers away in less than an hour.<ref name="Chappe DB"/>
