Greece
As the capital and largest city in Greece, Athens is known as one of the world’s largest cities and has a history that spans more than 3,400 years. With its long-standing history, many come to visit the porch of the Caryatids at the Erechtheum, the Temple of Hephaestus and the Odeon of Herodes Atticus.
