One of the great technical achievements that revolutionized the idea of time and space, opening a new era in the history of communication, is telegraphy. It is based on the transmission of electrical signals through a cable over long distances, allowing people to communicate instantly. The telegraph spread very quickly and a network of wires stretched around the world.
In 1837, the American painter and physicist Samuel Morse invented the first electromagnetic device for telegraphy, patented in 1840. To send messages by wire, Morse developed in 1838 a simple code of dots and dashes, which represented the letters of the alphabet, known as "Morse code ".
Both Morse code and the telegraph machine were improved over time, with the telegraph becoming the most widespread system of communication and information transmission for more than a century, until the advent of the Internet. The telegraph system consisted of a series of stations repeaters along the transmission line route. Each station had an operator who received and transmitted messages by telegraph. The Morse machine transmitted about 25 words per minute, which were recorded in code on a paper tape. The operator in charge of transmitting the message would decode it and write it on paper using a special typewriter.
In Bessarabia, the telegraph entered in 1860: on April 8, the Bender telegraph station began its activity, and on April 24, the one in Chisinau, following the construction of the first Odesa-Chisinau-Leova telegraph line. Currently, telegraph services have been discontinued. The only ones who still use coded communication are radio amateurs.
The Morse telegraph machine shown comes from the Osinoostrovsky electrotechnical plant, Soviet Union, and dates back to 1934. The exhibit was restored by Mihail Culașco.
The crypt and church from Niculițel – symbols of Christian presence to the north of Balkans

The monument was discovered accidentally in 1971 and was the object of several archaeological excavation campaigns. The martyr crypt from Niculițel, built from brick, is divided into two small rooms, one on top of another. In the upper room were found four whole martyrs relics, situated into a common coffin, made of wood, according to the orthodox known tradition, with the hands and the head west-oriented. All the martyrs had their heads cut; three of them were put in their places, while the fourth was put on the martyr’s chest. Three inscriptions were discovered on the walls of the crypt: “Here and there is martyr’s blood”, “Christ’s martyrs” and the last with the names of the four martyrs: “Zottikos, Attalos, Philippos, Kamasis”.
The archaeological and anthropological investigations established that their martyr act occurred during Emperor Diocletian’s persecutions in 303-304 A.D. Today, the holly remains are placed at the Monastery of Cocos, Tulcea County.
