Two ancient sites in Athens. Acropolis of Athens has 114 tickets and tours to book; Roman Agora of Athens has no online ticket listed. The table and the two notes below put them side by side; the full pages have what to see, the ticket and the timing for each.
The Acropolis of Athens is the limestone hill above the city crowned by the Parthenon, the marble temple of Athena built between 447 and 432 BC. The Propylaea gateway, the small Temple of Athena Nike and the Erechtheion with its porch of maidens share the summit, while theatres and sanctuaries line the slopes below.
The Roman Agora of Athens is the marketplace built with money from Julius Caesar and Augustus in the last decades BC, a short walk east of the older Greek Agora. Its star is the Tower of the Winds, an octagonal marble clock tower that survives almost complete. The site is small, central and quick to see.
