Télégraphe station
Télégraphe () is a station on line 11 of the Paris Métro in the 19th and 20th arrondissements. It is named after the nearby rue de Télégraphe, which was once a chemin de ronde (a raised protected walkway behind a battlement) of the park of the Château de Ménilmontant. Its name comes from the optical telegraph invented by Claude Chappe (1763–1805) in 1792. This was the first practical telecommunications system, but was eventually replaced by the electric telegraph. Chappe installed the relay station, containing the telegraph's apparatus which he called a tachygraphe, on this peak of 128 meters altitude. History The station opened as part of the original section of the line from Châtelet to Porte des Lilas on 28 April 1935. On 1 April 2016, half of the nameplates on the station's platforms were temporarily replaced by the RATP as part of April Fool's Day, along with 12 other stations. It was humorously renamed "#TWEET" , a reference to the evolution of text messaging in the 21st century and as a tribute to Twitter. As part of modernization works for the extension of the line to Rosny-Bois-Perrier in 2023 for the Grand Paris Express, the station was closed from
