the tower was only being used as a television and radio broadcasting tower, being open to the public only during the TIF as an observatory platform, with the original 1971 rotation mechanism still in use. In the 1970s, during the first attempt to complete a state funded analogue mobile telephone network, the tower was used to mount the antennae for the Thessaloniki network. In 1983, the observatory's rotation mechanism was jammed, forcing the observatory to remain closed until the 2005 renovation and causing the lasting urban legend that the platform does not rotate (as of 2022 the renovated mechanism does in fact operate normally). From 1988 and until at least 2010 the first floor used to house the main office of the Thessaloniki Radio (94.5) which also maintained a recording studio in the third floor, and the fifth floor housed a TIF-OTE joint television station used to broadcast Palais-De-Sport events and sports games. The second floor was used as an art gallery, with the OTE-ordered electronic music piece "Communications 1970" composed by Theodore Antoniou accompanying a painting exhibiion. 2005 renovation-today In 2000, the original 1969 TIF-OTE leasing contract was expired and TIF regained full ownership of the tower and its facilities. However, TIF re-leased the tower to OTE with a new contract which specified stricter leasing terms and was set to last until 2024. Following this new development it was deemed necessary to proceed with a full tower-wide renovation and modernisation project. The renovation study was completed in 2003 and work was completed in 2005. The rotation mechanism on the observatory floor was upgraded to modern standards, and the top floor was re-opened to the public year-round as the seat of the SKYLINE luxury cafe-bar. The broadcasting towers for the Cosmote cellular network were mounted on the main antenna mast and a new lift system was designed, effectively restricting visitor access to the deteriorated mechanical levels, the abandoned second floor art gallery and the first and fifth floor radio-television stations which are now only accessible by the old entrance gate. The tower remains one of the most recognizable landmarks of the Thessaloniki skyline and has been featured in a number of promotional campaigns such as the 2018 Coca-Cola Thessaloniki collectable bottle and poster combo as well as foreign films set in Thessaloniki such as the 2022 production of the Bricklayer remake. Ownership The OTE tower is owned by TIF-HELEXPO, the
