Optische Telegrafenlinie Metz–Mainz, optische Telegrafenlinie
The Optische Telegrafenlinie Metz-Mainz was a network of stations equipped with movable beams and telescopes to transmit messages over long distances. The beams could be positioned in different configurations, with each arrangement representing letters, numbers, or entire sentences.
The telegraph line opened in 1813 as an extension of a French system that had existed in France since 1794. The station in Stadecken-Elsheim was destroyed by the French in 1814 as French control over the region ended.
The station served as a military communication hub during French control of the left bank of the Rhine. Visitors today can understand how these locations represented advanced technology in an era of rapid change.
The site is easily accessible and stands in an open field with good views of the surrounding area. Visitors should note that the station has been restored but access may be irregular, and it is worth checking ahead about opening arrangements.
The stations could transmit messages in just two to six minutes over a distance of around 225 miles, which was extremely fast for that time. This speed was only possible because each station immediately relayed understood signals without waiting to decode the message.
