• A city located high in the Andes Mountains, Cusco was once the capital of the legendary Incan Empire. Not much is known about the city’s origins, but it is believed that it was built in the image of the puma, an animal sacred to the Incas. Either way, it is clear that the city was constructed in adherence to distinct urban planning. Cusco was advanced both economically and administratively. Heads of household were expected to pay taxes, and city officials used the money to build infrastructure and provide food and security to the people in times of need. It was also a hub for mathematics, astronomy, and calendar systems. Many ruins are located just outside of the modern city center, which also offers plenty to do and see.

• Before Alexander the Great founded it in 331 BC, Alexandria was already an important port city due to its location on the Egyptian Nile Delta. Alexandria was once a premier center of knowledge in the ancient world. It was home to a vast library of scrolls, one of the largest in ancient times. The library stood as a symbol of culture and intellectual achievement, until it was burned down in a fire that Julius Caesar himself started.

Centuries later, Alexandria played a significant role in Napoleon’s military operations, also due to its central location.
