Spreading its winged roof on a hill above Faliron Bay, this Renzo Piano building, surrounded by a vast park, made a big splash on the Athens cultural scene when it opened in 2017. Architecture buffs will love seeing the structure. Otherwise, check the schedule for arts events by the grand pool or at the National Opera of Greece, inside the complex.
In addition to regular public transport, you can use a free shuttle bus, departing from Syntagma at Ermou. It runs several times a day on weekdays, and every 30 minutes 9.30am to 11pm on weekends.
