Step-by-step explanation:
In Percy Jackson and the Olympians, Mount Olympus is described as looking like an Ancient Greek city to Percy. One reason for this is the stone amphitheater built on one side of the mountain. Mount Olympus looked like an Ancient Greek city to Percy because of the stone amphitheater and the open-air market.
The ancient Greeks preferred to use the natural disposition and geography of the land when building, and the theatre of Dionysus was situated on the top of a hill, utilizing the downward slope as the seating area for the audience. Another reason is the open-air market filled with colorful tents, which is a common feature in ancient Greek cities. Finally, there is no mention of a hippodrome or a coliseum, so these options can be ruled out.
