4. Book a free tour (in English) of the Stavros Niarchos Foundation Cultural Centre and learn the backstory behind the sustainable design of this new Athens landmark. Browse the collections at the National Library of Greece, join in a free outdoor session of yoga, tai chi, Pilates or aerobics, or enjoy one of the free concerts, outdoor movie screenings and exhibitions hosted at the centre.
5. Take sanctuary from the urban hustle in Athens’ gardens and green spaces. Hike up Lycabettus or Philopappou Hill, or catch your breath (and maybe a picnic) in the National Gardens.
6. Channel the Olympic spirit at the futuristic Athens Olympic Sports Complex in Maroussi, designed by Santiago Calatrava for the 2004 Athens Olympics. Walk, run or cycle for free around the premises surrounding the stadium and stroll through the highly Instagramable Wall of Nations. (Please note that the Central Stadium and the Cycling Track of the Athens Olympic Sports Complex are closed indefinitely, as an extensive maintenance of the stadium is scheduled.)
7. Watch skaters ace their routines at Athens' first digitally-designed skate bowl, Latraac, in Keramikos, where a cool tribe of artists and musicians congregate for all-day breakfasts every weekend.
