Explore Athens, one of the oldest cities in history and one of the most cosmopolitan cities today. Start the tour in the city center with a walk around Syntagma Square, the largest square in Athens, where you will see the neoclassical building that houses the Parliament of Greece and the Tomb of the Unknown Soldier, guarded by the Evzones. Next, visit the National Gardens, the former Royal Gardens, completed in 1840. Then, head to the Presidential Residence, the official residence of the Greek President, before visiting the Panathenaic Stadium, where the first modern Olympic Games were held in 1896. Continue to the Zappeion Hall, a beautiful neoclassical mansion completed in 1874, before ending the day in Plaka, the “Neighborhood of the Gods,” with its proximity to the Acropolis and many archaeological sites, including the Parthenon, Erechtheion, Propylaia, and Nike Temple. Spend the night in Athens.
