company managing the Thessaloniki International Fair, and leased to OTE based on the 24 year long expansion of the original 30-year long 1969 leasing agreement. While the original contract specified that OTE could use the tower rent-free, the 1999-2024 expansion specified an undisclosed price for the ongoing leasing of the tower. Architecture and design The OTE tower is a mix of modernist and futuristic architectures. It is designed around a main spire containing the elevators and emergency staircase. Surrounding this structure are several large discs of varying diameter which include the tower's usable spaces: The first floor: a small cylindrical chamber used in the past as an office and conference room The second floor: a two story high cylindrical structure with the emergency staircase looping around its edges, used in the past as an art gallery The third floor: cylindrical chamber used as a recording studio The fourth floor: main observatory level, houses the Skyline revolving restaurant The fifth floor: a small barrel shaped space, used in the past as a live broadcasting station In between the floors are small balconies which provide fire escape routes for the emergency staircase. These are only accessible from the main entrance (off limits for the public since the 2005 renovation), except for the one between the third and fourth floors which is also accessible through the Skyline restaurant.
