The tower was within optical range of other similar towers used for signalling with smoke during the day and fire during the night. Messages could be relayed very quickly and it is said that a message could be transferred from the shores of Asia to the shores of Europe within an hour. The towers of Vravron as well as Liada were also used to signal the appearance of pirates to the residents of the region. Local lore suggests that the tower was of Venetian origin between 1394 and 1405, but archeological investigations show that it was probably built by the Burgundian Dukes De La Roche (1204–1311) at least one hundred years earlier.
