Athens (Piraeus), Greece
Piraeus' giant port and naval base welcome you to the edge of the Athens' urban area. From there it's a simple jaunt to the centre. The majestic ancient citadel of the Acropolis dominates an elevated platform and is a constant presence as you explore the city. The wonderful remains of the columned temple of the Parthenon - which date back to the 5th century BC - stand here, representing the pinnacle of classical architecture. Or rise up Mount Lycabettus, to be rewarded with perhaps Athens' best panorama of the Acropolis sitting high over the city on its grand stage. See the marble horseshoe of the Old Olympic Stadium, where the first modern Olympics were held in 1896, for more of the city's enduring legacy.
