The new Exhibition Centre, the METROPOLITAN EXPO, is the biggest in Athens, covering an area of 110,000 sqm. It is located in the northwest development area of the International Airport of Athens "El. Venizelos". The METROPOLITAN EXPO consists of four (4) exhibition buildings, all of which are located on the ground floor and occupy in total 50,000 sqm. There are also two conference rooms sitting 600 and 400 people respectively, plus a number of auxiliary facilities which ensure the smooth operation of the centre. The outdoor parking spaces are for approximately 4.000 vehicles. Since it is located in the wider area of the International Airport of Athens, special specifications have been taken into account with respect to the operational design of the Metropolitan Expo Center.
