Athens Olympic Complex
Lonely Planet review
Crowned by the striking glass-and-steel roof designed by Spanish architect Santiago Calatrava, this showpiece stadium complex is where the main Olympic action took place in 2004. The vast site includes the futuristic, shimmering Wall of Nations and hosts major football (soccer) games, sporting events and concerts. There are guided tours for groups (minimum 15 people; per person €3) but independent travellers can wander around the site.
