The Agora was ancient Athens’ heart, the lively hub of administrative, commercial, political and social activity. Socrates expounded his philosophy here; in AD 49 St Paul came here to win converts to Christianity. The site today is a lush respite, home to the grand Temple of Hephaistos, a good museum and the 11th-century Byzantine Church of the Holy Apostles, trimmed in brick patterns that mimic Arabic calligraphy. The greenery harbours birds and lizards. Allow about two hours to see everything.

With its serried rows of white Pentelic marble seats built into a ravine next to Ardettos Hill, this ancient-turned-modern stadium is a draw both for lovers of classical architecture and sports fans who can imagine the roar of the crowds from millennia past.

The Plaka is the oldest section of Athens. Most of the streets have been closed to automobile traffic, though you should still keep a watchful eye for a speeding motorcycle or delivery truck. At one time it was the nightclub district, but most of these closed down when the government outlawed amplified music in the neighborhood in the seventies in an effort to get rid of undesirables. The strategy was very successful and it is now an area of restaurants, Jewelry stores tourist shops, and cafes. Though it is quite commercialized it is still a neighborhood and arguably the nicest neighborhood in central Athens. Most of the restaurants are typical tourist places but the quality of food is not bad in some of them and if you follow my leads in the restaurant section of this guide you should have a few enjoyable evenings and not be unpleasantly surprised by the bill or wake up with a gastro-intestinal disorder on the day you were supposed to visit the Acropolis.

The Castle of Thessaloniki, also known as Heptapyrgion or Yedi Kule, is located on a hill above the Old Town (Ano Poli). Its location gives gorgeous views to the city, the port, and the Aegean Sea.
