Posidonia is the world’s most prestigious shipping exhibition. It runs in even years at the Metropolitan Expo next to Athens International Airport. The 2026 edition, held from 1 to 5 June, sold out 50,000 m² of space and attracted exhibitors and visitors from 140 countries, with around 2,000 exhibitors and 25,000 visitors (estimate).
