For the Geo Quiz, we are looking for the largest city in a North African country.
It is a major coastal oasis, making it a perfect spot for growing olives and other fruits and vegetables.
The city is divided into "new" and "old" quarters.
The old quarter is home to the marble Marcus Aurelius triumphal arch and the renowned Camel Mosque.
You can also find the royal palace belonging to the late Libyan dictator Muammar Gaddaf there.
Tripoli is the answer to the Geo Quiz.
