Telecommunications Museum of O.T.E

The OTE Telecommunications Museum is housed in a building at 25 Proteos Street in Kifisia. It opened in 1994 on the first floor of the building, with its collection of exhibits occupying an area of ​​500 square meters. Over the years, as technology evolved, telecommunications equipment became more compact, allowing the Museum to expand into the building’s second floor. Consequently, the museum now occupies an area of ​​1,000 square meters. On the first floor, there is a collection of telephone sets, a model of the cable-laying ship ΄΄Thales o Milisios΄΄, OTE network equipment, teletypes, and more; the second floor houses a section of the automatic long-distance telephone exchange for Athens and Thessaloniki, as well as a section of the local telephone exchange for Athens. Additionally, the first television studio acquired by OTE in 1968—coinciding with the launch of Greek television—has been preserved in its original state and is on display at the Museum. Admission to the Museum is free. And so, on a sunny day in September 2026, we decided to visit the Museum. Upon reaching the entrance, we paused for a few moments… to pay tribute to the thousands of workers who, over many years, toiled to ensure that messages reached every home. Thousands of kilometers of cabling, the installation of various devices and infrastructure—spanning more than a century—gave rise to what we call telecommunications in Greece today. Ascending no more than ten steps, we reach the first floor… a thrill runs through you the moment you catch sight of the vintage equipment—dating from 1890 all the way to the present day—and the emotions run even deeper when you come across a bicycle from a bygone era, once used by a staff member to deliver telegrams from house to house… As we enter the second floor… we’ll stop talking now and let you enjoy the rest through the photographs.
